Very cool atmosphere and art style, and a surprisingly large level for a game jam game!
A few minor issues that I encountered:
- The mouse sensitivity is very low on high-dpi displays when the mouse is captured.
- There’s no indication that smaller blocks can be picked up; maybe a sound cue when failing to pick up the larger block could work, to show that the key can do something to cubes?
- You can soft-lock yourself in the tutorial by clipping the box through the ground
