Ninja Pizza Girl is a good speedrunning 2d platformer. Controls could be tighter and it’s a not a highly polished game, but I had fun with it.
Each level has several paths, so you have to explore to find the better routes, and it requires some memorization of enemy placement if you want to improve. If you dislike Sonic you’ll dislike this, but you’ll not necessarily like it if you like Sonic as, again, Ninja Pizza Girl is kind of a niche game that’s not highly polished.
You can unlock double jump, which changes gameplay quite a lot, but none of the levels require its use.
The game offers great control over difficulty. You can separately increase or decrease game speed, number of enemies, how much time you have to complete a level (e.g. you don’t want to deliver cold pizza), and a couple of other settings I don’t remember.
