The moving platforms felt a bit slow but only in the beginning when you didn't have any aerial movement options. Once you got the double jump and air-dash you could breeze through areas without worrying about the platforms too much.
Overall there weren't any other hazards than radioactive sludge that you had to avoid; I guess if enemies or traps were present then the platform speed might've been more problematic. Worked for me though and had a lot of fun timing my jumps and abilities!
Other than that on level design, some of the areas had vertical platforms that I guess were meant for you to come back to once you got the climbing ability, but I kinda ended up aiming for the little sliver of ground they had on the top because at the time I had no idea a climbing ability existed.
Once again, this was probably one of my best experiences on the game jam! Great job!
