It's a simple concept, and movement/dashing feels really nice. Just running around and jumping was a lot of fun tbh.
I feel like this game needs quite a lot more juice to really shine. I didn't feel like I was doing any damage at all, the fire rate is really low with no indication that you can't shoot - so I found myself getting hit only because I couldn't shoot at the right time and didn't really have the information to know whether or not I could shoot.
Enemies have way too high health, I don't feel like I've got a shotgun I feel like I've got a water pistol.
You do manage to get a lot of work out of the simple 3D shapes, and the fog works well for a sense of atmosphere.
FYI this doesn't run on firefox!
