Slope Glitch (tutorial in description)
There’s like a 50/50 chance it’ll work, that’s why it took so long.
1. Start a normal game of Slope, and hit a red block (less likely to work if you fall off or hit a red wall in a tunnel)
2. Spam the “enter” key really fast as soon as you die, so a new game will start instantly (or you could just spam your mouse over the “again” button).
3. Enjoy your glitched and impossible world.
What I see often is:
-The ball doesn’t load and you instantly die
-The starting ground doesn’t load and you fall infinitely, due to the glitched world
-Tunnels will be glitched into each other
-There will be random slopes to the left or right of the stage
I think this happens because the game doesn’t have time to delete the old world, so it generates the new world inside of the old one.
