Very well done! You can understand this game's theme without knowing the jam, and the controls are not laggy. 

Highscore: 18

Overall concept is solid. I really liked the background changes when landing on the next platform, and the size changes when idling, both of which add life to world. I would say the flying mine things were a bit annoying, especially since they seemed random and when timed wrong always cause you to restart. Music and sounds were nice though. Well done!

Interesting take on platformers.  I really like the use of complimentary colors on the background each time you touch a block.  Cool touch there.
