Awesome game concept! could expand slightly, love the action and the sound effect, but here some part that i think can be improved.I think many have mention about the restart button and larger grid.One thing i experience is that the game get increasingly laggy as i play on, i need to refresh the page to stop the lag, i don't know whether this is an issue with my laptop or the game memory. lastly, PLEASE fix the bug where character stand there after last stage is cleared, i would love to see the ending. ^^
-_- okies.. decent game until... when i play until level 52, a bug hit me, i could not fire my machine gun, which max upgraded -_- my turret aren't strong enough.. so T_T
