Very solid art and music. Sound effects didn't do a whole lot for me, and the narrative wasn't super clear as to why I was suddenly turning evil. What power was I given? How does my character relate to the bosses? "Show don't tell" is a popular phrase, so maybe consider baking the story into your atmosphere and background and level design?
Encountered a bug where I beat the Creator but the battle didn't "stop." Then I ran into a stationary explosive and died LMAO
Bosses don't really "interact" much with the player. When I bum rushed them with my claws the battle was over in 10 seconds, except for the scorpion. Had to be a lot more careful with him, he's very slippery. I could use more feedback when I hit a boss, and more telegraphing of what's an attack and what's moving.
Overall it just needs these little polish things - I see great potential in this. Well done!
