For anyone interested in seeing me play other games, I'm separating all that content out onto a second channel. So, this current channel will be ONLY MARIO. To see me play other games, please subscribe to this channel instead: youtube.com/@CarlPlayin42 -- I renamed "Larl Longer" to "CarlPlaying42." I will be posting over 50 hours of edited Minecraft hardcore mode first playthrough content there (I've been having SO much fun with it on stream), but now it won't show up on the main channel for people who aren't interested. On the other hand, I also have a hilarious and highly recommended troll level coming up, which will be here on the normal channel. So, just subscribe to whichever channel has the content you want to see! Thank you all so much for watching my silly videos, I am currently between science jobs as my previous professor retired, so all of your support is greatly appreciated ❤️️💛💚💙💜
