Good bite-sized jam game with just enough progression.
I actually enjoy the billboard assets, the rocks remind me of Okami's. Also seems like a smart way to prototype quickly in 3D.
I enjoy the nods to the retro FPS style. Have you ever tried Trenchbroom? It's a tool for making Quake style maps, including stuff like the Valve 220 format. You can import these to a modern game engine with the help of some middleware/baking tools.
