Orbital Bullet - Around the World in 80 Kills
There's no shortage of sidescroller roguelites out there. This one... this one is a little different. You're still scrolling to the sides, but every level loops right back around. So you can shoot right, and it comes back on the left - assuming your shots go that far. I used a shotgun and killed most enemies from three feet away defeating the purpose of that magic, but it still looked cool while I was doing it.
