Hey!
I played the game (both the "normal" version and the Tempting Tendrills too) and it looks promising! I love the themes and the overall idea. I don't know if you plan to have several levels that could give a way to include the Tempting Tendrills in the main game, but it might be a great way to add different settings and possible kinks.
If I may, something I liked from Tempting Tendrills is the fact we see other characters trapped there. It helps giving the feeling we're not alone as the setting suggests. It's a nice way to make it more... Lively?
Anyway I'll keep following the project and play the next updates!
