1: Fine.
2: Walls feel too low, you should extend them upwards.
3: Could make the ending further, otherwise fine.
4: Fine.
5: Pretty boring, could make it so you do a catch on the last wall.
6: This is a really big jump in difficulty, since you go from t3 to t5. End is really far and the setup for the triple is awkward. Maybe move the tube closer, just experiment around basically. Could also swap this and jump 8.
7: Might be a me issue but for the 3rd last wall you could move it on the right side. 4th last wall should be closer to the previous one. Also for future testing add some nonade walls in between the shootable walls since its tough to determine where the next one is.
8: Add some lines at the end so its easier to aim, otherwise fine.
9: Fine.
10: Banger jump. Only issue i have with it is i bonk sometimes if my walls are too good so could extend the ceiling by just a bit. Make the last wall a different color so its easier to tell as well. Also a small nitpick but move the tele destination right next to the starting wall.
11: Needs a lot of changing. The 1st section is ok but the wallshots after the triple feel insane. Either extend the wall or move the ending closer. You can also easely cheat it with a resync.
Hopefully my feedback helped
(also it felt like a t5 map)
