Surprisingly great Wipeout TV Show inspired free 2D platformer. The physics and handling are pretty loose, but that only makes it feel like an authentic wacky obstacle course. There's a lot of fun courses here (including 10 dlc ones that were a nice addition later on) that are all really fun to race through multiple times as you first figure out how to tackle them, then improve your time on the leaderboard in subsequent runs. Despite its origins as a free ad game, this game kicks a lot of ass.
Underrated gem IMO. For a free game, it's got a lot of replayability and it's a riot online with both randoms and friends. Found myself getting pretty good at this one back in the day, with it being one of my first experiences with time trials and competitive online gaming. Still regularly revisit it even now. Screw Fall Guys, this is the Wipeout game we really truly deserved.
