Reviewing games for the finish your game jam! I like the grass! It looks very nice while also being performant.
The inventory system also is a unique take on the 'tetris inventory'. I do think some more could be put in to make it understandable, like cleaning up the collision shapes, but as this is a pretty limited demo, it's understandable and conceptually neat!
The setting is certainly one that is under explored in games and media, hopefully you can find a way to make it enjoyable!
