I gave up on Level 14. This Game was unexpected fun, Great Job!

The only minus are the controlls, they need some re-work.
I mostly died trough transitions between z,x,a and s then trough the level difficulty. There are many different keyboard types and with a german one it's particullar difficult to koordinate. On top you can jump by using the top arrow which is not mentioned. I noticed it in level 14 by misstyping the controlls. It would be really usefull to knew it before.
