>Perhaps in the starting area, you can have a demo battle so you can get the feel of how to win before you enter the demon world.
I'm hearing this a lot, it's something I'll 100% add in future games. The texture variation or how most of the walls are the same is due to it being the first time using the engine with a lot of plugins that alters how the engine handles walls. There is more variations in the paid version starting with the third dungeon of the game. I wanted the first two dungeons to have walls mostly the same for a sense of dread while exploring since the MC/player is trying to adapt to the new world.
Thank you for your feedback and for enjoying the game. I'll take note of everything you said for future projects.
