Some criteria I'd like in a game:

Games that are a semi-short speedrun, 30 minutes max.
Popular to speedrun.
Not insanely precise, nothing even close to SMB1 but I would like there to be a few glitches in the run, not just beating through it as fast as possible.

I see you already ran Minecraft Classic. Some categories of regular Minecraft would fit your description.

I'm looking for something a bit less luck based, also preferably a Nintendo game. Even better if it's Wii, Gamecube or Switch.

Super Mario Odyssey or The Legend of Zelda: Breath of the Wild. Both are highly optimized games and fun to run.

Out of your two options, I think i'll go for BotW just for it being under 30 minutes.

Facing Demons is a simple game that only takes 20 minutes, but it's only for PC

But its so easy game

I can do PC but it doesn't seem to have many runners, making it harder to learn how to speedrun.

@cheapeliquidcheapeliquid Wait 2-3 months for 24 moderators to review your run, no thanks
