I couldn't finish the game myself since the controls feel too floaty to make the precise jumps, especially with those spiked balls. It feels like when you let go of the jump button, you're still ascending even if I'm just trying to land.
The collision on the hazards also doesn't have to be 100% precise. At that point it feels like I just barely graze a spike and it kills me. it'd be nice if the collision for those were a little smaller to give the player a bit more leeway.
I like the take on the time limit being indicated by how slow things move, but after a certain point everything moves so slow you just cant do anything but sit and wait until the time scale reaches 0. Maybe at that point on you could increase how fast the time slows down so you don't have to wait for so long?
Overall its solid but could use some gameplay adjustments.
