Have seen some people a bit confused by how to beat it so here's how to beat it (only use this if you're stuck though)
1) Place a block at the bottom of the unjumpable wall, to the bottom left of the lowest gradiented block.
2) press ';' then 'r', noticing which tile moves upon pressing 'r', put a block underneath said tile (gradient tiles are sand, sand falls as many blocks as it can until it hits something)
3) Notice how it's currently impossible to get through, go to the y line of the map which prevents you from going through, press 'v' and while pressing v press the right arrow)
4) Like the previous one, however here you need to find the right y *and* x. find the tile in which you can access both the row and collumn, then press and hold the v key, along with the up then right arrow to solve it
5) The first of the 'harder' puzzles, for this one move to the air tile to the bottom left of the blue thing, and v+up arrow, then go up one row and v+right arrow. if vortexes are in any way changed you instantly leave the map editor.
6) No hint for this one
