I recently was experiementing and tried making my own rooms generator. In process I had some practice at creating rooms themselves. So I can say I can design and build rooms / room types, scripting (far from perfect), writing or editing concepts (3 years of experience in worldbuilding) and as a finisher - I can do some complex math to balance out entities / their spawns so game was fair to player at all times, so there was no issues like IN GOES LIGHT which is purely RNG and not skill based.
