I really enjoyed this idea. The "guns push you" mechanic has been done before, but this was definitely a neat twist on it. The graphics were polished and everything fit in really well, the colour scheme was interesting. The sound wasn't obnoxious. Really good job overall. I think the only thing I didn't like was I felt like you should be able to autocollect the coins (have them automatically fly into you), because coin collecting itself isn't interesting mechanically or design-wise, really, and it slowed down the pace of the game a lot having to go and grab all the coins each time you killed something otherwise they would disappear.
