A bigger variety of tentacle? That does sound fun... Also, thank you, I have a lot of ideas that I like to think are good(as well as some ideas that I hope bring to life myself... as soon as I find the motivation.)
Sounds like a sound plan, art be pretty important for adult games. Though I have played some pretty saucy text only games too so not a must have. But improving art is such a slow process, at least for me. If you really have the burn to make a game, I’d take a part in a jam, they really helped me to push from just prototyping to actually finishing a project. Doesn’t have to be perfect or even good, but finishing something feels so good, and you get the motivation boost from the feedback and seeing someone actually try out something you’ve built. Practicing and building just for yourself works for a time, but motivation can really start running low at some point.
