Excellent game, good job!
The art style and music are perfect for this game. The concept is simple but works well!
However, there is a bug that makes my frog shake when I get out of the map. And it's quite disturbing...
Thanks for playing my game! Yes, the boundary check logic is pretty bad, it's the first thing I want to fix when I get a chance!
This bug should be fixed now! Now you can play without feeling disturbed :)
