I though to myself that this was a much more relaxing endless runner than another one I played earlier in the jam, then I found out I could switch dimensions and found myself in a world of fiery death!
The parallax background in the forest-y area is nicely done except the foreground doesn't also use it, causing that to stand out. The speed of the running is actually quite sedate in both dimensions, so even when there's fire everywhere there isn't a sense of danger or excitement compared to if things were going twice the speed.
I really like the death sound the character makes, by the way!
