Awesome game, movement feels smooth and quick, only lacking a double jump in my opinion (although it would be too much with 3 wall jumps, maybe an optional trade off in the upgrade shop where you trade one wall jump for a double jump would be fun?). Shooting feels explosive and damaging with the revolver and shotgun. Nailgun is somewhat meh. Still, overall it's awesome and I'm defiantly buying the full game after playing through 100% of the demo.
