v1.1.0 - Summer update!
Heya all! To celebrate the summer, here's a little update of Light 'Em with 6 new summer-themed constellations ☀️ (And by the way, I've also included a few fixes, and the possibility to reset tutorial progress , if you wish to restart it to remind you of the basics.) So if you wa

v0.5.0 - Refactor of the "auto-prod" system
Heya all! Thanks to everyone's continuing help and feedback, I've done a new update for Light 'Em to (try and? ^^) improve the auto-prod system for the 6 star types. My two main goals with this update were: to fix the bug that occurred around LVL 175-176 of rate upgrade and cause
Heya all! Thanks to everyone's continuing help and feedback, I've done a new update for Light 'Em to (try and? ^^) improve the auto-prod system for the 6 star types.
My two main goals with this update were:
to fix the bug that occurred around LVL 175-176 of rate upgrade and caused the auto-prod of the star type to sink back to a lower value
and to make auto-prod more interesting overall (since up til now, active prod was usually way more useful, unless you had very specific skill tree upgrades + run bonuses)
To that end, I've decided to refactor the auto-prod system as follows.
Starting from v0.5.0, instead of having an "auto-prod rate" that is then transformed into a per-second auto-prod amount, I've decided to use an "auto-prod multiplier".
So, basically, now, the auto-prod value of a star type is computed from its active prod, just multiplied by a factor. Upgrading the "auto-prod" of a star type grows this multiplier, gradually making the auto-prod value closer and closer to the active prod value... until it even outgrows it and you start to super-boost your auto-production! :)
Full disclosure: I've tried to test this new system as much as possible but, as usual, balancing everything is kinda hard - so I'd love to get your opinion / feedback / advice on whether you think the current balance is OK, or where it could be improved!

v0.4.3 - Blueprint improvements + Multi-prestige!

Heya all! Thanks to everyone's continuing help and feedback, I've fixed a few more bugs, and added some features, in Light 'Em these past few days :)
Features
Isolated stars: I added a rule to prevent constellations from getting validated if they contain an isolated star (i.e. a star with no links at all). You'll get a warning, and you'll be blocked from validating until every star in your constellation has at least 1 link.
Constellation blueprint limits: When completing a constellation blueprint, you'll now have a hard-limit on the number of links you can create. If you try to abuse the system by over-adding links, the game will block you and give you a warning that you're exceeding the expected number of links.
Multi-prestige: If you've over-accumulated enough skill points to reboot multiple times in one go, you won't need to go through reboot multiple times anymore. Now:
You'll get a little indicator next to your reboot button to tell you the number of reboots you'll do.
If you do more than 1 reboot in one go and you've already unlocked Astral Pacts in your game, you'll get "bonus rerolls" to reroll the bonuses for a given run :) Note: These rerolls stack up, and they're saved with the rest of your game data (if you've saved your game with a version of Light 'Em that is v0.4.3 or more).
Refactors
Constellation thresholds-related skills: I have slightly increased the values granted by the "Celestial Expansion" and "Astral Bridges" skills (that increase the number of stars and link length threshold for constellation auto-validation). Hopefully, they should support bigger constellations now! Note: But rebalancing is always difficult, so feel free to tell me what you think, if it works, etc :)
Fixes
Misc:
When you're renaming a custom constellation, you won't get a contextual menu if you right-click on the text input anymore!
I improved the formatting of large numbers to use mantissas as simple as possible. This should avoid getting things like "10.0M", and intead give "10M".

Heya all! Thanks to everyone's continuing help and feedback, I've fixed a few more bugs in Light 'Em these past few days :)
Refactors
Telescope: The price increase of the telescope has been severely softened - i.e. the cost will grow way more slowly, and you'll be able to use the telescope more times before it becomes really expensive. Note: The behaviour of this refactor will be weird for already saved games (since, sadly, the price of using the telescope is saved in the game's file, so it will be the cost from before this update)!
Fixes
Market & Casino: Both those special features have been fixed to scale with the current autoprod/game state. 1. Instead of giving fixed (way too low!) rewards, the casino will now offer to bet (and consequently gain) money or skill points relative to your current autoproduction and skill points amount. 2. The Market should now properly compute the up/down derivation of your initially invested value :)
Misc: When using the telescope, the constellation blueprint should directly stick to your cursor instead of spawning in the top-left corner of the screen.
Misc
I've slightly re-adjusted some star production growths... still rebalancing the best I can! ^^
You can now rotate constellation blueprints (given by the telescope) clockwise, too, if you're using a mouse!

Fixes

Star upgrades: Fixed the sudden "downgrade" on Pulsars when reaching level 7 + Rebalanced the star powers to get a better evolution curve.
Reboot & Market reset: Added a reset of any invested funds in the Galactic Market upon reboot - along with a confirm panel to make sure you don't forget about them :)
Blueprints: Now, if you've placed a blueprint but put stars completely outside the indicated spots, the blueprint will be removed and refunded.
Load optimisation: Loading levels (in particular large ones) should be faster :)
Misc: Other small fixes in UI (especially for French version)

v0.3.10 - New Blueprint QoL Features + Fixes & Improvements
Heya all! Thanks to everyone's continuing feedback, I've fixed/improved yet a few things in Light 'Em this week 😀 Features: When you use the telescope, you can now use the mouse scroll or to rotate it. This can be useful if you need the blueprint to fit in the middle of your exi
Heya all! Thanks to everyone's continuing feedback, I've fixed/improved yet a few things in Light 'Em this week 😀
Features:

When you use the telescope, you can now use the mouse scroll or to rotate it. This can be useful if you need the blueprint to fit in the middle of your existing constellations!
Then, once you've placed a constellation blueprint in your sky, you'll be able to zoom in and out on it (again using the mouse scroll or ) to better see the links it contains, in case some spots are too close to each other to be readable. Hopefully, this will make it easier to use the telescope and progress in your codex 😉
There is an option in the game's settings to enable or disable the sky erase on reboot. It will be disabled by default, meaning you'll initially keep all constellations and stars when you reboot, but you can choose to toggle it on to start fresh with a new canvas each time.
Fixes:

Constellation reward (ongoing): I've started to improve the way the constellations' value is computed to be more rewarding. (But I still need to decide on some rules here and there, so it might evolve a bit more in the future.)
Settings panel layout: Improved the layout/spacing to better accommodate the growing number of inputs.
Market computation: When you transfer stocks into the market and retrieve it back instantly, you'll now get the exact sum you transferred in.
There are still some bugs that have been reported and I haven't managed to fix yet, but I'll try my best to take care of those in the upcoming days/weeks! Thank you again for your help in making the game better 🙏

Heya all! Thanks to some cool feedback on Light 'Em since I've published it this morning, I've managed to do a few fixes and improve some stuff. The biggest refactor is that now, you DON'T LOSE your constellations upon reboot! They'll stay in your sky and you'll get to keep worki
