Just gave it a quick run. FYI it works on Mac using Wine.
Feedback:
-Nice art and sounds.
-The inertia on the player feels a bit weird maybe it should go to full speed a bit faster.
-The attack of the enemies is a bit too fast even in slow motion and it makes the game more about shooting while moving until you hit them instead of a proper skill, maybe an animation for when they are about to shoot could solve this.
Good game!
