Yeah, it works great for porting as well. I tried it on the assembler sources of Prince of Persia for Apple ii and went from nothing to basics being playable (with a few bugs but still) on modern Mac with SDL graphics within a day.
Yup. Still fighting some collision bugs, but it mostly works. I'll post it when it's complete. What I actually wanted to do is try to put fluid movement into it - something closer to Dead Cells, just for fun to see how it would change the feel of it.
