That was a really cool game with interesting mechanics. The mouse movement works really great and feels fluid and responsive, the only issue is accidentally moving the cursor outside the game window (I have 3 monitors). I think there is a lot of potential in the way enemies work too.
Visually speaking, it looks great, the pixel art is nice and clean and the lighting effects are just so effective at creating a cool atmosphere and making the game look dynamic.
All in all, you did a great job on this entry, there's not much to criticize, really :)
