Touchpad Heroes (Mobile, Corona SDK)

Hey all!

Me and some of my friends have been developing a mobile game (iOS/Android) titled "Touchpad Heroes". At the moment it's being developed as our senior project but we're hoping to polish and release it at some point after we've graduated.

I've uploaded to youtube a video which shows off some of our art and gameplay:

You can download our latest build here:

And to run it you'll need to download the Corona SDK Simulator here:
https://developer.anscamobile.com/downloads/coronasdk

Once you have the simulator running and the build unzipped, you'll simply have to go to (within the simulator) file -> open project -> Touchpad Heroes\main.lua

Directions: Simply use the Mouse as if it were your Finger (for touchpad devices)

I'm looking for general feedback, but specifically I'd like to know how you guys feel about the mechanics, the controls, and the art style.

Thanks, everyone, in advance!
