This is just a little thing I have been working on. It's pretty glitchy in it's current state, but it's a work in progress. I'm trying for a stealthy-assassin feel, and right now you can play through the first part of the tutorial. I assure you though, it was a fairly perfect platformer when I first made it, but then I realized that there wasn't any way to ascend without just normal jumping, but the problem was that to really implement that I basically need to re-create the entire movement scripts and I'm obviously too lazy to do so. So as with pretty much every project I make, it's less me trying to make a playable game and more me just messing around with stuff.
