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".
