I was pleasantly surprised by this one. The graphics and the name made me expect something unfinished and unpolished, but there's actually some really good stuff in here.
The game feels a bit like Enter the Gungeon or Nuclear Throne, and I was particularly impressed when I got to the boss fights! Those are excellent!
If you splashed some more polish on this, it could probably end up pretty good. The thing that bothers me the most is probably the sfx that plays when you shoot, that gets really frustrating after a while.
