I like the concept, the blood effects on the walls is a nice touch, but it's a little hard to get around and not being able to shoot up is quite annoying. It will make for a fun platformer/shooter once some things like movement are ironed out :D
Thanks for the feedback! Could you elaborate more on the difficulty of getting around? Is it the speed of movement, the jump height, the background opacity? Up shoot is a feature we planned to add but unfortunately didn't have enough time. What changes would you make to the movement system?
