Really enjoyed the visuals. The simple pixel art style with some of Godot's lighting effects did a lot to help elevate the graphics to the next level.
The concept was also really cool. It was fun trying to figure out how to use the room pieces we had to get to each next area.
This may be a me thing, but the physics were just a tad off for me. There were a few places that I couldn't walk through, but they looked like I should have been able to. Acceleration and deceleration on movement was a tad to slow for my liking, given how accurate some of the platforming sections seemed to require. I also thought I'd fall faster given how fast I decelerated in the air after jumping.
Again, these may just be more personal preferences for me, and I had a great time playing. Good job!
