Just asking because I don’t have a gaming system that I could speedrun with until weekends (for personal reasons that I shall will not speak of) and maybe at the very most something I could get used to very fast or at least easily

Other than subway surfers

I don't play mobile games, but based on the pc/web versions I recommend the games by Jussi Simpanen: Super Dangerous Dungeons Duke Dashington Remastered Total Party Kill Heart Star

The mobile versions of his games are generally more popular than pc for speedrunning.

please edit your previous post instead of double posting

but a good mobile run is cat bird

Check these mobile games that you can play on Speed running. Geometry Dash Slither.io Granny Rec Room Minecraft Journey Human: Fall Flat

They're fun to try haha
