Nice game, the grim art style definitely fits the game.
Though, the controls are, as the others have mentioned, is slow.
I would also like to be able to dash through the enemies. Right now if I'm being cornered by enemies I have no way to escape the barrage of enemies and projectiles incoming.
The intro scene is cool, but having to keep replay the intro scene is kind of awkward and it breaks the pace of the game.
The animations are very impressive, that must took a lot of work! I like how the stamina UI is incorporated into the halo. The instructions are very clear too.
Good work on the game!
