Well, I saw your gameplay video and must say the environment light was good enough.
I don't know why in my system that looks like too dark! you know the solution?

Hey Amin :) Yes, the team wanted to keep working on it after the jam to fix up some of the things we didnt have time to get to. This included more adjustments to the lighting. I believe the lighting adjustments had already been put in place before that video clip was recorded to provide a sample of some of the mechanics. (switching between your forms to fight different enemies, solving the soul gates etc)
