Really hard game but I managed to stick with it and got 611.9
Visuals are great, the smoky background effect is particularly nice and I like how the world lights up when you get your next ember.
I think a few tweaks would make it a little more accessible. The level transision is a little slow - its possible to fall down a pit in a room before the camera sees it which feels bad when you are expected to repeat levels multiple times and see this transistion. The camera on the later levels can get vertically confused, sometimes I was walking off the bottom of the screen and just had to navigate by memory/vibes. And the gravity when falling feels a little too powerful - it does make the jumping feel nice and weighty but just a little slower descent would make some of the final jumps a bit easier (especially the ones that involve sliding down a wall).
Overall enjoyed it though. I'm glad I stuck with it, thanks for making it.
