Troll maps are pretty awesome, but only if kept within reason and done well. Keep it within reason, I'd say.
A long-delayed update on my map -- I'll just mix my map with hub elements. Basically, you my map contribution will be the hub. There will be simple puzzles to solve along the way, and as you unlock new areas you gain access to others' maps! I'm doing this partly because I can't handle the workload of working on my new project (dubbed PRAmod for the time being) and building a brand new hub level from scratch, but also because it implements the idea of adding a Super Mario-esque feel to the levels.
So don't give up on your levels! Finish em up and let's finally get a release out there
