This is a nice little game. Not very special but an enjoyable ten minutes of your time

addictive! a heal function would have been nice, and if you want to make it even harder, let the asteroids bounce each other ;) alot of potenial in this game!

Nothing really good to say here. The upgrades don't seem to help a whole lot, and the waves get too difficult too quickly. Skip this one.

The upgrade mechanic was good, but the moment I purchased the 3rd level cannon it was unbeatable (at least in the 3 tries I played through); the 2nd cannon upgrade is focused and therefore easier to target and push back targets; the 3rd level, however, spreads the shots too wide and therefore you're shotgun blasting everything with no focus. This becomes impossible when any two targets close together come at the same time, because you can't shoot a focused shot at them as 2/3 bullets miss them until it's too late.

the controls are sluggish and this really isnt much for a defense game. no upgrades, no building nothing
