You are the black square. Use the arrow keys to move. Navigate green platforms, avoid red danger, and use blue springs for a jump boost. Features: - Mobile-friendly - Wall jumping - Going uphill (45 degrees steep at most) - Moving platform - WASD/Space bar compatibility I'll admit that the moving platform is a bit finnicky. But it works as it's supposed to, so no more should be said. To make a level, go to each sprite (except Player) and make a new costume. Design from there, and add your own style as well. I don't know what people see in trails. If you want a trail, add it yourself.
Credit to @XaosKing for the collision code, though I wasn't given the code. I found it in one of his projects. (I'm giving credit, this is not stealing.)
