Really enjoyed it. A mini-metroidvania where the player is under intense pressure to find exactly the right pathing. Very hard, I wonder if the default time should have been 20 for a game jam. I would have liked to spend slightly less time re-running the same very easy first 7 seconds only to be punished by missing exactly one jump. But the controls felt super solid, and I always appreciate when player instructions are designed into a game environment.
Agree with others, I was looking for some polish to push it over the edge (particle effects, more diverse lighting) but that's asking so much in 96 hours and it's only because what's here is so solid. I think it's a great use of the theme, and one of the better implementations of this idea that I'd seen. Nice job.
