Firstly the music is phenomenal, you did an outstanding job. Would be better if it didn't fade out but still, it's SUCH a groove. Secondly, the art and animation is also top notch and I love the retro theme. Lastly, the gameplay is pretty fun when you hit a combo, but I wish it was easier to consistently bounce on the creatures instead of hoping the game generates them close enough together. I love this game though it's great.
Edit: I just realised that you can time a jump to go higher. It became way more fun after learning that; I just wish that was mentioned somewhere in the game.
