This is kinda silly... but it's fun. I played the PC version from your site, and I enjoyed it. Good casual gaming, when you don't want anything too complicated. Why did you pick doors, btw? I mean, there's lots of things you could smash. Doors aren't the first thing that come to mind.
But this works well.
It starts rather slowly. Too slowly, in my opinion. For the first minute or so, I thought it was boring and I almost quit. Then the doors starting coming in multiple waves, with the occasional "not a door" to avoid. And it got a bit more interesting. So I'd recommend ramping it up more quickly. Just by a little, so you don't lose a player to boredom.
EDIT: I just played it again...and it seemed to ramp up more quickly.. so it's fine. Or maybe it just seems faster because I've had a glass of wine.
The graphics are pretty slick. But the music is VERY cool. I love that techno sounding beat. Is that your composition? It's very nice. +1 for that.
Nice game overall. It would work well as HTML5, so you might want to consider that. Good luck with it on the stores.
