Bugs I've noticed

1. Game bugs after completing random challenge. Game does not freeze but you can't get out from challenge end. 

2. Coffin / Coffin Air
- Coffin (ground) seems to be delayed like 2s after an input from gamepad.
- Coffin Air bugs when you press input in air it counts as "Trickless air". Coffin air must start from ground coffin and jumping from ramp to count. I think it wasn't like that earlier.
