11-20 map pack is up. I'll go to work on RTTE021 soon because in my new opinion people who give up on a fun project they started suck balls.

Just thought i would throw an update here

Removeing the goo and putting port walls to get back to the start of a room would work as a checkpoint for longer maps, i did that for 002, i think i would need the beta map genrator to put checkpoints in, i will make a map pack for 1-10 coming soon.

Yeah I understand.
What you can do is collection (in steam workshop), so you gather all your maps it's easier for players.
And, there's not way to create checkpoints in maps?
I tried your other maps

I like making my maps long, trust me. Testers that fall in the goo alot like them short i find. if i use to manny items when building a map it can't be created. To avoid that stress i brake down my idea's and land up having to make smaller rooms. Thankyou very much for giveing me my very first comment. For you, i will make 015 much longer, i need feedback to know what people want, my next map will not have manny items so it can be much larger. you may wanna check out "Grab the cube first and you win!" it is my first co-op map, had only a few items, it's a long and challenging map that started me on this idea.

fun but too short :/
