It's very addictive, the problem is that the game window opens at the bottom right of my screen and I can't move it, so I can't see anything at the bottom of my screen, but that's probably just a me problem. Oh and also I have no idea how to buy stuff from the shop thing at the start. Great game though.
Okay never mind, I just have to to change my display size every time I want to play the game, and there should be sounds when you get hit and some way to notify you when your health is low, like in other game where your screen goes red when you have low health. Just some suggestions if you're still working on the game.
