Hello! Going by your username, it looks like this is the same project as in this thread? Is it okay if I merge the threads?

The low resolution in these screenshots puzzles me, but mostly I still have the same opinions as I think I mentioned on your SAGE demo... the JJ3 demo isn't really the pinnacle of game design, and the level geometry in particular feels very dated these days, with the repetitive textures and low-poly walls. It's impressive (maybe? I don't know anything about 3D game design) that you were able to port all the levels perfectly, but I hope you find a way to improve on them, not just copy them. The gameplay too.
