Hey, I found this game Crazy Cubes (https://spikygames.itch.io/crazy-cubes), and it's just a great game. It's a 2D platformer, it's very tricky and precise and probably made for speedrunning, since it even has a lot of speedrun-specific features. Honestly I don't even know why it's not on the website yet, it would be so much fun speedrunning this and seeing new records and strategies of people. But anyways, I just made my account so can't request the game, if you find the game interesting, feel free to give it a go, and request it yourself if you liked it and want to see a new leaderboard of it
