I loved this game; it's so refreshing to play a game jam game that doesn't try to do everything great within the first 10 seconds! Instead, it takes a slower, simpler pace and rewards you for your persistence and time playing.
My only gripe was that the frog has an absolutely super high jump! It would have been more realistic (and tense) to have the frog jump only when collecting an item from a certain height and below (say halfway up the screen)
But overall great game!
