Soon you'll learn how underwhelming a lot of these projects are going to be. A project made entirely on the pun "Super AGAR.IO Bros." back when it was still popular. I could never find a fitting scrolling engine for the game, and I stink at scripting, so it was canned. I never had a solid concept in mind, but one was going to be how you could climb up any wall, or ceiling, if a wall led up to it. But I didn't know how to script that. Another was going to be how all the coins would be those small pellets that you eat to increase your size, and you'd have to take on all the enemies, but you could only beat them if you're bigger than them.. I dunno, it was a pretty dumb idea from the start
