ummmm
its a good game, but the problem is that in my computer, the keyboard works, but the keys still get stuck and i end up going out of control up or down. Im using another browser, but still doesn't work, maybe its the graphics that slow down my computer responses, maybe add a lower quality button. Either way it's not a bad game, i even like the idea that you get to upgrade a lot and make your weapon more powerful throught the time, but it would be nice if you wouldn't lose the upgrades that you have and that you wouldn't die in the first hit. Maybe add a life bar?
