Didn't get far before I encountered a bug unfortunately. I entered through a door to go to the next area (the third area only I think) and when it loaded the next area I was gone 0.o
I like the idea of it though, reminds me of the 2D Zelda games.
It's pretty cool, some potential here. (sounding like some moronic critic :P) Anyway, i like it, add some upgrades, possible a axis for the turret, something to protect? 3/5 from me. I would love to see some updates or something. good job.
I really enjoyed this game on my first playthrough, and my second, third, forth and so on. I think you get the idea. 5/5 from me and I myself don't see the need for upgrades. this game is briliant the way it is!
