Hey there,
There is bug i noticed after submitting, which makes the UI hidden and prevents it from telling you the game mechanics.
To interact with objects you can press the left mouse button. To pickup stuff you need to press E.
To open the chest you need to hold a key. To mine the crystals you need use a pickaxe. To power the diesel generator you have to use the diesel canister. And to explode the tnt you need a lighter,
The elevator can only be used after turning on the power and mining all crystals.
I will fix it after the jam
