Soo I'm trying to reduce the tile length by a factor of two, and it sort of worked. I'm not planning to make any platform as thin as a single tile length, so it will be glitchy if you fall through one, but don't worry about that. What I am worrying about is that for certain platforms but not others, if you stand on the very left of it, you can fall through it sort of. 0 for editor. Space for changing brush. Click to draw in editor! Arrow keys to move. C for clone. I for infinite (sort of) clones! If you press I twice you get it 10x faster somehow but it gets boring. T for teleportation.
This went surprisingly well, taking only 3 days or 1-3 hours and with only two bugs which were really obvious and fixed in less than a minute and one that was a little annoying (this is my first time building a platformer without tutorial). I'm planning to build a tile puzzle platformer out of this.
