Hello everyone! Sorry for the prolonged silence but we're undergoing some internal rearrangement so we took it long! This is a bugfix/QoL update which fixes a lot of bugs, balances the gameplay experience, improves things here and there and prepares some ground for future changes, here is the full changelog:

Chest Interface now is twice as big for better organization
Health regen from equip now triggers after 5 second without taking damage from monsters
Implemented item sets bonuses : this features allows to give specific bonuses(and effects) when a specific set of items is equipped
Created a set for each Uber boss equip drop, now the single equip pieces give less light value, equipping the full set gives the full light value
Added tooltip symbols reference(accessed by Help pane, F1, then F2)
Added light value to tooltips of armor pieces
Added tooltips to some unclear potions
Some mobs are now able to see through player invisibility
Thorns damage on monsters is now mitigated by their defense
Thorns related potions have been buffed
Adjusted some thorns bonuses from equip
Fixed critical chance of weapons which wasn’t working(all had 0 % critical)
Fixed bug which wasn’t updating collections when equipping items or pets
Fixed bug which didn’t consume proper amount of items when using simple craft
Fixed bug which allowed instant forge crafting
Fixed a crash when dropping an item stack into an occupied space in some circumstances
Fixed quick stack from forge which didn’t properly move items
Fixed craftbook key which was working in creative and crashing the game
Fixed Metal Feet potion, now it properly makes you immune to spikes
Fixed open save folder option which wasn’t working
Fixed a random crash when browsing collections
Fixed a crash that occurred when destroying some growing plants
Fixed truth table device which wasn’t working as intended
Fixed some OpenGL issues on certain graphic cards(now game requires OpenGL 3.2)
Changed Bottomless Chest UI color to match the graphics
Fixed some weapons which had wrong animations
Fixed some graphical glitches
Fixed hacked item stacks larger than 999 items which could crash the game
Added additional keys to bindable keys
Added an option to shop help for some items in their tooltips
Changed double confirmation dialogs to be more secure
Upgraded build tool for Windows build of the game
Since we had to change the toolchain used to compile the game make sure you have Visual Studio 2017 redistributables if you're playing on Windows! Steam should automatically prompt you to install them in case. The update is rolling out on Windows with macOS and Linux versions following in the next couple of days. The next big thing will probably be official controller support since many of you requested it! We're already working on it and we hope to share further details soon! Happy mining! Pixbits

Hello everyone! Today we're releasing a new patch which includes Linus/SteamOS support! This version is still experimental, so if you are using this os please report any bug you find. We also added new actuator blocks! Pistons, advanced pressure pads and retractable blocks combined with wiring will let you create complex machines which interact with the world. We'd love to see your creations with these new mechanisms. Last but not least we added new crossbow weapons, explosive arrows, improved spears among with many reported bug fixes/balance tweaks. We hope you enjoy this new version. Have fun! ENHANCEMENTS

Hello miners, it's patch day! This version adds new procedural mobs, a scalable viewport option, new potions, new spear and bow mechanics, treasures drop rate tweaks and many more features and fixes. The new spear weapons mechanic is experimental and the whole spear graphical approach will be tweaked in the future, we're thinking about increasing their length to make them able to reach more distant positions while making them less effective for short range combat. The new procedural mob generation is experimental too, we tested it with slimes to understand the potentiality of generating different flavour of mobs by composing parts, we'll extend this feature whenever possible to other creatures if it satisfies us and especially you! The Linux version is under heavy development and we're in a good state so hopefully we'll soon release it! Have fun playing! ENHANCEMENTS
