Can you become the bouncing champion?

I made this game in two days just for fun, using C programming language.

[This version contains some bugfixes]

It is supposed to be difficult. But there is now a Cheat code enabling infinite tries. See below.

If you happen to beat all 20 levels, feel free to post a screenshot of the ending screen! 

Tipps:

Press A just before the ground to bounce slightly higher

Hold DOWN to bounce weaker

Hold SELECT in title screen until you hear a sound effect. Now you have infinite lives! :)
