Roguelike in a nutshell. Nice!
The art looks like you made it all by yourself and that is really impressive. The game looks incredible.
I just must admit that I did not manage to survive more than one minute. The amount of "bad-fluffy-darkness-dudes" was overwhelming and attacking did not feel like having a lot of impact so I just spammed my mouse button to kill the dudes which just lead to emptying the oil :(
