i have an idea for building a level but can never execute it correctly

anytime i build i never like what im building however if i like the build then i start to run out of ideas for how the level should continue so how do people overcome this??

this is the level im building right now but it just dosent look good at all here is the level: https://www.bopimo.com/levels/5709

Yeah I could probably help with the level especially since even the first challenge is kind of pointless. I can very easily skip it with a double jump and a dive.

Your building is similar to levels to do quickly without much difficulty. If you want an idea from
my opinion makes a level similar to this:
https://www.bopimo.com/levels/1725 - make a speedrun map but with a gravity twist

if you need a building reference for a moon related level:
https://www.bopimo.com/levels/6953 - the terrain is done in a moon related setting too

things to note:
avoid doing very tall walls to section off areas with moon gravity you can infinitely climb walls
