Hello Pixelation

First post here - So please be merciful

I need help for my 2D Android Game. The Name is "Commander Bean".
It's an Jump and Run Game with an bean in laser action.
The game is for free at the moment. But I think about a "PRO" version.
(why i can't attach some pictures (?)...)
Here is the PlayStore entry:
https://play.google.com/store/apps/details?id=cb.je.demoThe mainproblems are:
- Main Menu is prety ugly
- Different controls design
- And Leveldesign
If you think you can help me in one of this points - please contact me.
Best regards
Yoshi
