Hello, and, first of all, thank you for your comment.
Assuming that you're asking about the camera, I was inspired by old dungeon crawlers, or, in other words, 'Ultimalikes'. If you'd like some pointers, there is currently a Dungeon Crawler Game Jam on itch, although I'm not taking part right now. Probably the most recent popular rendition of the genre would be the Legend of Grimrock series, which I have enjoyed greatly.
