Title mostly says it. I'm planning on converting one of my unfinished projects into one of it when I have the time.

I don't plan on making pixel art, I would like to focus more on storyline, and a moderate parkour. Unsure if I should add in some adventure items to open all those doors etc. Should I?
Also, quick question to add on, how important would you rate decorations such as clothes on mannequins, small aesthetics such as lamps on tables from 1-10.

Thanks :]
