Exoracer

I think it's a fun game to play if you're into speedrunning or enjoy building levels yourself :) there's official levels (with seasonal ones built by players aswell) and a huge number of custom levels with daily levels aswell. The gameplay itself is similar to something like Geometry Dash in that there's only a single key you press, but there's mechanics like swings and gliders etc. that make it fun. a lot of the official levels have been optimised to basically frame-perfect inputs though, which makes it hard to get in like the top 100 on most of them. The active player base currently isn't as big as it was before but there's still a good number of people active playing and making levels :) I think it's listed for a fair price, and I recommend it :)

Like Geometry Dash but brainrot

Best game I have ever played
