Not bad, pretty nice game modes. I recommend to overwork the menu design a bit more. It is not clearly enough where to switch to the mainmenu and to other screens at the first time. Also a in-game help would raise your score. The next part I recommend is to polish the graphics up.
I see much potential in this game, it could easily get 6-7/10 Stars when you rework the graphics.
The music isn't annoying to me cause it fits to the game.
You can combine your existing achievment values to let the player get newgrounds achievements.
Just keep a bit working, the jam has not ended yet.
Summary
+ Gameplay
+ Different modes
+ Challenging
- Graphics could be more polished.
- UI design could be improved (Homebutton, Mutebutton as mentioned should be visible)
- In-game help would be good
