What was the most frustrating thing you ran into while making your games?
For me, it was definitely all the pain that comes with making your own custom character movement system. For my game HIKEBOY, I created a custom climbing system, which required me to do all sorts of funky stuff with sorting layers, custom colliders, character sensors, and one long C# script featuring about 3 million else if statements, each with far too many && conditions. I'm honestly so surprised I got it to work, lol.
How about you?
PS: post a link to your game so that I can check it out :)
