The art was nice, the animations were smooth and the gameplay was simple but worked.
I really disliked the camera, as for some reason the square to show where you were facing kept wobbling around, basically having permanent motion shaking. If the game was any longer, I feel like I would be puking. The camera also feels way too smooth, I get that you’re trying to show the scene in front of the player, but in combination with the camera moving when the player moves, as well as with the mouse moving, it just makes it a mess. Perhaps a delay before the camera actually moves, and a range of player/mouse movement that the camera ignores would be good.
Should try to at least put some sound effects in, as I feel something as simple as your attack having a sound effect would be good enough.
I would see this being on minigame websites if more content and fixes were made.
