Cute squirrel! I like the addition of the wall-jump, particularly being able to wall-jump off the falling blocks--there's a fun bit of risk/reward trying to scale the blocks mid-air.
How do you get to higher levels? I escaped a few times but feel like I must've missed something. After each round it still said level 1.
Also I hit a few rare physics issues, where the squirrel occasionally passed sideways through a block as it was landing, or couldn't fit up through a gap that visually seemed passable. Standing on blocks always worked though.
All in all, this is a fun bite-sized challenge, and the combination of the falling blocks + rising water + escape hole on top work well together to form a narrative.
