I agree with you on this, it's been two games, and the next one is already touching similar fetishes, also, while they can switch it up and spice things up regarding the tentacle stuff, it already does seem to have a dungeon style on it...
Making the game not so much just "tentacles" can do a few things, like pushing the creator a bit out of their comfort zone (nothing bad with tentacle games but I'd personally rather more MC and NPC interaction, Demon Slayer Shion already had an amazing amount in it), give more lore around, and potentially allow for a bit less of just random maze that you have to be going around, the art of this dev is amazing, but the only downsides are how the beginning is 70% tentacle dungeon, and 30% interaction with some others, and how, for many, going in circles around the map truly is annoying if you want to progress (the dev had to upload a map of the areas because of how repetitive and annoying it could get to try to pass from one place to another, nothing bad with a bit of a maze area, but when the entire game is focused around going aimlessly from one place to another like this, it can become frustrating for many)...
