This level's alright. There's still cases of weird transitions, bad layouts, mixing of tilesets that shouldn't mix, and bugs.
However I do like the idea; it's creative, pretty well implemented. It definitely shows improvement over your past levels, but still needs work.
I think you need to lay back on posting a lot of new levels, Matty. You don't need to prove to everyone that you're a good editor by posting 10 levels a week. In fact, that just leads to rushed, shoddy, and incomplete levels. Just because you created a level doesn't necessarily mean you should publish it (I have
many levels that I've created but haven't published, especially my early ones.)
Put more time into level editing before posting levels. Create a bunch of full levels over the next few weeks, then pick maybe
one or two you feel are the best, and post those. This will not only allow for experience in level editing, but will also make them more polished, as you can compare them to your previous levels. And you wont have a bunch of mediocre levels just floating about. Posting every level you've made just looks like you're just posting levels for the hell of it.
And instead of posting new levels all the time, spend that time refining and editing
one good level at a time. It would be good to see your creativity show in a quality, full-length level.
At least this is what I would recommend doing.
