This is a very polished game! And have so many levels! Everything is polished, sound effects, particles, animations, graphics - even the score screen is awesome! I don't see a theme here, but it doesn't matter - it looks and plays really well :D
Thank you so much Pawel! And thank you for organizing this jam too, I had a blast! :)
For the theme, you simply need "one too many" bounces to survive the level :P
