Okay I've check it out, and here's a few thing I should say about the game. It seems and has the potential to be a fun party/co-op games with the current game mechanism right now, but not so much for single player with the lack of check point/health/extra health and that you've to restart from the beginning when you lost. I suggest you make it more like Metal Slug, where the player has a chance to gain extra health/lots of extra health so they can keep continue playing until the end or try to make it like Castle Crasher, where you can put some short checkpoint so that player can continue from those check point they've reach.
In a wacky party sense, it's a good game. Perhaps makes the character more bigger so player are able to see it more easier.
