I use f6/f7 all the time, but I hate doing it because I know I'm going to die, and many times. Then the waiting to reload and die again. I have no problems with your maps, I just don't like doing maps where the chance of dying is prevalent around every corner. My style is more in the pure puzzle arena. Just because I don't prefer your maps doesn't make them bad maps, I don't know how good they are truthfully, I just know that I'm not very interested in finishing them to find out.

yes it s kinda fark, i didnt realize the unportable tiles make the rooms so dark,but in my opinion is playable, also i dont have portable surfaces in secret dark places. all interest stuff for solving the puzzles are noticable.
@mechtakendall if you use quick saves/loads(F6,F7) death traps are minority imo. and i keep complexity of the puzzles simple, for balance of the big map. the progression for solving it is kinda linear. the majority of maps i have play have more death traps than this map.
i respect your opinion, thnks for feeedback.

Too dark and full of death traps. Not a fan of this kind of puzzle, so I'll have to pass.

Hm.... in this darkness i did not realized that i was in 3 rooms :D
I solved but i don't think that i used all things as it supposed to used. I did not use a speed-gel and a funnel, and in some places i used three stacked cube as a stair.
