Overall it is a pretty nice map, but there are a few complaints I have about the map.
The teleports feel a bit far apart for a map of this difficulty. There are some large blocks that I would think would be a check point due to being so vastly different in size from the blocks in their general vicinity, but then end up not being check points.
The texture for the boosters is hard to differentiate from the normal texture at a quick glance, so I had a few moments of hesitation on my first run just looking where I am supposed to go not realising a block was a booster for half a second or so.
There are some blocks that have the texture that you used for check points, but are not check points. I don't know if this was intentional or if it was a mistexture (due to say, removing a previous tp), but I expected them to be check points due to this texture and they weren't.
Coordinates for those blocks are:
[-861 2822 167]
[4571 1367 -96]
[3308 1485 -35]
[3407 -7498 -1570]
[3415 -8658 -1570]
[13595 861 -1687]
4. The block at [2845 -1398 -70] is the only check point that doesn't have the check point texture, so it feels off. Use the command "setpos" ingame followed by the coordinates (but without the brackets surrounding them) in order to teleport there if you wish to see which block the coordinates refer to.
Overrall, the map was fun to play and I liked the aesthetic of it.
