I made UnsFuck Engine, an platformer engine I made for my game. There isn't much to talk about here, except that it can do slopes, it has neat placeholder character for you to use, mobile support, and other stuff I didn't mention.
CONTROLS: W, S, A, D, Space L. Shift.
To go through the menu, use your mouse
...Unfortunately, this engine uses assets I made for my game, music and everything. Please remove these assets if you end up making a game out of it.
P.S. To make spritesets, use the tool I linked. It requires nodeJS to run, and it's quite easy to use if you know your way around a terminal.

I made maps using an app called NotTiled... Because I don't have a PC, and that's the only mobile map editor.
