Just a quick update. I went and counted the non-repeated screens for my level so far, and it looks like it will be in danger of breaking the minimum screen count of 300 for the EPIC KS level competition.
Attached is a screenshot of an area that I worked on today. It utilizes a tileset that I developed from scratch for this level. Once I'm done with this area, I will have two more to complete before the level itself is finished.
