There was nothing wrong with Minecraft Parkour that isn’t also a problem for everyone else. Bumps just don’t work very well.
Instead of getting upset, you should put your energy into achieving whatever it is that you desire. I had already told you how to fix the game on your general topic.
It took me a while, but I was able to fix it using the techniques I described. Bumps for the platforms have been removed (and replaced with math), but I left the Bumps for the star, flame, & mob as those seem to work fine. I also tweaked a few things, fixed a few bugs & took some creative license with the flame as having it stationary didn’t seem quite right for the game play (and was nearly impossible to get past)
