I actually have gotten a lot done on that
I reworked the character sprite to be 4x8 instead of 5x8, so that his left toe wouldn't stick through walls.
I created a door animation like the original shift's
Diagonal Key jumping
I am reordering the levels
I made the custom level have custom input built into the main menu
I m planning to make the editor have a bit more checks to prevent illigal levels
I also need to expand the engine so keys can move any block, not just solid empty
