Nice job on this game. It's a fun little survival game. Wasn't a big fan of the controls as I'm on a keyboard that doesn't have arrow keys and have to use a key modifier to get there. So ended up using my wife's laptop.
But that aside game is pretty fun! I like having to turn the turret and then put each module on their own slot is a nice concept! Once you get more stuff the game starts to get crazy and I was enjoying myself. Good SFX and music. Enemies were interesting. Keep expanding on it and I'd take a second pass on your controls!
Cheers :)
