You did an awesome job with this game, simple and fun. The art in general is pretty cute, the puzzles are right at the point (for me, level 4 was the hardest) and its well done. Just some details: when I jump at the edges, it fails sometimes , and at the last level, I can pass the walls to take the flag (probably something with the collider in both cases).
Well done and good work! I really had a good time with your game!
If you want too, please stop by our project to take a look :D
