I love the deranged look in the mouse sprite's eyes!
The controls were surprisingly tight and reactive, so the platforming felt very fair and nice to play. Splitting the 10 seconds into 4 bites was an interesting take , though it perhaps sort of sidestepped the limitation a bit.
I liked that restarting is very quick, which makes mistakes feel less punishing. Also, the enemies that steal cheese is an interesting mechanic. However, it does create situations where you can't actually beat the level anymore -- which means either the enemy has essentially the same effect as killing you, or worse, you don't know whether you can still beat the level, and have to maybe fruitlessly continue to find out. I can't really think of a good way to solve this though.
Anyway, an endearing platformer, I thought.
