Nice simple idea, well pulled off - I liked it! I might've missed it, but I couldn't see how many lives I had left anywhere - which meant I was just shooting without any kind of lose condition in my head..

Nice simple game :)

Great art! Nice work dude!

Smartphone + autofire  ;)

I think I'd totally play that on a smartphone.

Also liked the graphics. There's one thing about the shooting though. And you are far from the only one guilty of this, but if the best strategy is to just have the shoot button pressed forever it sort of takes away its purpose. I get one might not want to hammer on it, but joint solution to this and somepx's comment would be to let X-down start a 3-5 shots burst.

Thanks :) 

I have to adjust it a little.

More weapons and enemies in the next update 

Great pixels! I'd recommend lowering enemy HP and increasing the amount that spawn to increase the fun :)

I really enjoyed this game, excellent graphic. Could have been better with ammo and different weapons! ;)
