Pretty good prototype. Got murked by the Yellow King, right at the end of my first playthrough, who decided to teleport inside a wall and mind explode me. The animations and art were pretty good, I'm a big fan of Post Void and Gun Godz so this felt right at home. The weapons still need a bit of tweaking though, as another commenter put it it'd be nice to have an auto reload. Also a couple of the weapons (either of the energy/laser weapons and the triple shot rocket launcher) are horrendously underpowered. They also don't seem to have any sound effects either which is jarring when compared to the pistol which does, but I guess that's already on your to do list. But strangely never saw the 3D skeleton guy, the town nor the crystal cavern from the pics. Could chalk it up to bad luck but I played through it 3 times and never saw any. Anyways, really fun game, keep it up!
