CTM map area ideas

HEllo everyone,
A few of you know that I started making a custom map in my freetime between working on the server and homework as a way to vent my anger(traps, Traps EVERYWHERE MWAHAHHAHA) but I have one problem. I dont know what type of areas to make. I have these in progress atm

1. Undead Caves: easy difficulty First area, Caves with vanilla zombies and skeletons
2. Firest: Forest with lava instead of water and netherrack in place of GRASS (note grass) Major WIP

If you dont know what A CTM Map is look up Vechs superhostile and play one...you will die...a lot. But anyways I need ideas for about 18 more areas (I know a lot)

This is a longterm project for me (3-6 months) and I am determined to finish it one way or another

Thanks for your help

Maybe some floating stuff? Without bedrock so if u fall u'll lose everything that is in ur inventory

^ Similar to how's idea. A floating parkour city with a LOT of arrow, tnt and lava traps.

The idea isnt making them rage quit lol

how about one were their are 2 blocks but the blocks are so far away that you would never be able to get on but you could land 1 infront of it....

This isnt parkour map guys

it isnt parkor its just impossilbe and you can throw a skele on the 2nd block
