Heroes vs. Mechs, my new free tower defense game for iOS

Hey guys,

This is a game I've been working on for the past 3 months using Corona SDK. It's a free tower defense game where you build turrets to fend off incoming waves of SNES-style fantasy sprites. There are 10 maps and 5 levels of difficulty.

The main inspiration was Robo Defense. I really liked how you could place your weapons anywhere on the map and have the enemies react to your decisions, so I wanted to make a td game like this, but with more maps and more enemies.

If you've got a few minutes to spare and an iOS device handy, please try it out! It's compatible with all devices. Would really appreciate any feedback.
