Honestly, combat & movement feel pretty good and and it's very comparable to what a normal engineer would put together after 6 weeks. The hard part, when making games at least, is figuing out what makes things fun and (more specifically when it comes to RPGs) how to do the scaling. Both of these are pretty hard and require a ton of experimentation.

Since it's vibe-coded, I was really hoping to see some AI-generated storylines (turn `go to <x,y> and do z` into a fun quest) and more story. AI is surprisingly good at generating passable prose, certainly comparable to a middle-of-the-road RPG.
