It's fine, but I have a lot of complaints.
My first complaint is speed.
You go as fast as fucking Sonic The Hedgehog COMBINED WITH AN OVERDOSE OF STEROIDS
My 2nd complaint is jumping.
The jumping mechanic is SO BAD, on certain platforms, you can't even jump!
My other problem is about jumping. How you build height, you basically keep spamming 2 keys.
My OTHER OTHER problem is how, when you stop jumping, you basically lost because you can't jump.
My last complaint is the PLATFORMS.
They are as slippery as ICE TOPPED WITH OIL. Even when you stay still, you still fall off the platform!
Good concept, but made horribly.
