My 2nd game I've ever created, and I uploaded a second platformer test, because originally these zones were in my other platformer test, but glitches within my game prevented the zones from showing up. If you ask me, I'd think that these are the best.
TIP: If you get stuck on (or even in) a platform, my advice would be to hold down the left or right key (or all the keys) and try to press space. If that doesn't work, I apologize, but you have to start the game all over again.
Helpful reviews would be greatly appreciated, and thank you for playing!
