Just had a look at your game.
It's a good start. A simple theme and clean, simple graphics.
You might want to refine the hit boxes for attacks on the enemies and the players because I found that I could only kill 1 or 2 enemies before I died, or give the player more health. I think this could be a fun game, it doesn't need all the sparkly bits we all aim for, just a little refinement of the combat.
