Hi! Sorry for the delay. Sound its not perfect, but It isnt terrible either. It sounds okay at Max volume so maybe higher sensibility would be appreciated. Music and sound effect are not really of my taste though.
I would say that the crank input is way too sensible. Its hard to be precise.
Regarding Gameplay, I think It should be a bit slower, like It is plants vs zombies. I must confess I havent read the "how to play" but sometimes It ends before I realize what happened on screen.
I think the concept has so much potencial, so keep It Up!
