I'm sorry everyone, I didn't realize this thread got some attention.
Thanks for feedback, but I'd say this project is on hold, but not just because.
It's not forgotten, but I've been working on another project. but still, for the dungeon crawler, I decided to go 3D, or at least give it a try.
I wanted to work on some 3D modeling, that's why. It will be long time until I go back to this project but here's something I got out of it.
