The idea is really nice, totally in the theme and works perfectly.
The game has an ending, different characters (only played one :p), and it's really fun! A bit long to go to the end tho, but the "last part" is not boring at all (and really fun).
But it's always hard to manage the difficulty/time to beat the game in a jam, so it's not a real problem!
The arts are really well made, nothing to point out, it was a pleasure to play!
