Cool! I gave it a play. I appreciate that you did something cool with the life in 2d theme, though I will admit I'm a little confused by the mechanic. Would be cool if there was puzzles you had to solve by switching back and forth between 2d and 3d. In this version I felt like I was just switching to 2d very briefly just to reset my timer.
Regardless, good job on the jam. I liked the character model. I'm sure you can take the concept further if you want.
