Is there any plan to create a full-fledged level editor and update this engine so that we can play levels from the level editor? This way, we can share levels through the Internet.
There are tons of levels available already thanks to the existing editors in other versions, but the catch is that right now you have to compile them into the game yourself. Unfortunately I don't have the bandwidth to add a run-time level loader, but the source is on GitHub, and if someone sends me a patch, I'm more than happy to merge it and create a new release.
