Had a blast trying to get pars for every course !
It made me think of SEUM: Speedrunners from Hell or a tamed down version of Ghost Runner.
The only issue I had is that sometimes the wall jump icon would appear but I couldn't wall jump, and once I got softlocked between a platform and the wall (in the "floor is lava" part of the course where you're left with only air dash.)
Otherwise great concept ! Would love to see this get more levels !
