This is really really fun, and feels really good to play with all of its audio and visual effects giving oomph to things that happen. The graphics are really good too, though in gameplay terms sometimes it can be nigh impossible to pick up the bullet after you've shot it if enemies swarm in its direction. I also agree with JBroook that it's a little slow, perhaps those two issues can be fixed in tandem by tuning speed, or something of the sort. Regardless, this is really really good!
