This adds one of the most-requested upgrades: the Material Belt lets you have 10 rows of material shortcuts on the bottom of the screen! Now you can have a lot more control over the selections of materials you have available!
This upgrade requires Molybdenum, so you should be able to get it in the second underground biome.
Also, this update adds 3 more languages: Ukrainian, Italian, and Czech!
And the following additional things:
Made the Steel Alloy reaction not increase the amount of Iron in the world (consumes Carbon, but that is reclaimable)
Added a new room type for the lower level of the limestone caves that contains Cobaltite, to reduce the probability of not finding it
Increased the power output of the Turbine and Solar Panel pixels
Quality-of-Life: doubled the Ruby drop-rate from Granite
BUGFIX: Diamond now builds into Diamond Wall (not Diamond Deposit), which can be crowbarred
BUGFIX: prevented buying a recipe or a tool-bearing upgrade when the inventory is completely full
BUGFIX: prevented empty tooltip appearing over undiscovered map rooms when searching for materials in the World Map tab
Misc: added a texture for lava so it stands out visually in the lava caves
More stuff coming soon! :)
