Pretty good small game. Things I liked:
+ player sprite is adorable, good animations
+ gfx overall is pretty good
+ jump physics and overall controlls are nice
Now the complaints:
- no damage indication when you fight frogs
- when timer runs out, nothing happens
- error message when you move to the next level
- seams appear between tiles
- sometimes running animation keeps playing instead of idle animation
- usualy it's Z - jump, X - attack, not vice versa, but that's not a big deal
