In 2020 (2019?) I was looking for some cool Nintendo DS homebrew for my flash cart, one of them being DsDoom. It only had the shareware WAD preloaded and wasn't the smoothest in terms of framerate, but I was still satisfied. Shortly after that I bought both Doom and Doom 2 on Steam and the Switch, and the rest is history. Got into map making around that time as well, even if I didn't release anything then.
