The CPC shader is QUITE AWESOME ^^
First impression is super great with both weapons and intuitive controls, sadly room layout is always the same and it is hard to take advantage of it.
Why not make ennemy slower and make bigger rooms, so you can take some space and attack them while they try to reach you?
Audio visual is there, there is something to do gameplay wise, keep it up! A slow and considerate hack and slash is definitely something I want to play, but ennemys should be manageable. (now we end up in a pile in a corner :) )
