You said somewhere that this game is meant to run on a second screen, kind of like a screensaver. Thats why i think a way to hide the HUD, healthbars, questprogress and stuff like that would be a nice addition.
U might wanna lower the attackrange of the turret, because if you dont want to be overrun by enemies (squares ;) ), u need to lower the lvl of them so much, that u will never see any of them on the screen. and i think its quite strange to see the turret fire into nothingness
the gameplay, as it is, is awesome. but there are too less upgrades and too less different enemys, an also it's much too easy :/ . but becaue its the best gameplay i've seen in a flashgame 5/5 and favorite :-)

I agree! I've added it to our list (but have no idea how hard it is to do yet).
