It's a really cool idea, and great to see that your critter manages to make better and better jumps. However, the levels all feel a bit the same, and so after 1-2 of those the fun starts stalling (although the critter keeps getting better, you don't have those 'Oh, cool!' moments where you feel a sudden increase in skill from the critter). Maybe give it more actions to work on, and focus on learning one thing, then another, then combining them?
Really love the concept and would like to see this taken further, great job for a 1-week jam!
