Why you are using slopes WRONG! (And how to fix them)

In order to find levels for my series "Unknown levels" I have to play a lot of recent levels, so I come across a lot of levels that have the same problem: Weird hitboxes in the wave parts because of upside-down slopes. I hope this video will somehow find it's way to new creators to help them make better levels.
I hope you enjoyed the video :)
