I made a tutorial game/proj a long time ago for Kongregate's API named Carpal Clicker :P This gave me some PTSD.
I really want to hear some Stereo Audio in games like this! There aint a whole lot going on mechanically, but a good audioscape can make anything interesting! :)
Could definitely benefit from a reticle.
Controls feel pretty responsive, I love wobbly potato-guy, and the game flow is clean and easily understood.
