I'm really glad I could be (one of) your introduction(s) to hypnosis! I really think it's a fun thing that's not explicitly explored nearly enough, especially in the context of self-hypnosis. I try to make this game as player-paced and beginner-friendly as possible, so I'm ecstatic to hear you feel this way!
And your suggestions and criticisms are also super appreciated! I plan on completely removing the alert feature for the next build to go back to automatic induction starts, while also including the bit you're talking about where you can exit out of an induction and re-enter it any time, at your pace. Again, despite being a game about hypnosis, player choice is an important aspect! (hence the fact there's a million toggles in the game, lol)
As a character designer, I always like to make characters that are as wildly different from each other as possible, in terms of both visual style and personality. A lot of the feedback I've gotten is about the stark contrast between Faustus and King Cobra, and I really appreciate you saying so specifically about the visuals, too! I'm going to see if there's a way I can meld things together more for future builds, or see if adding more character variety either muddies the pot or makes the contrast less surprising.
And thank you for asking about nsfw content! It's a big thing on the back of my mind in making this game, and I'd love to talk about it for a bit. For a TLDR (which if you've read this far, you probably don't need), the answer is maybe! But here's the longer and more in depth answer:
I'm always going to include the 18+ warning in this and any other hypnosis project I make just because my interest in hypnosis is tied to a kink, and I think just that connection means a level of consent needs to be present. Even if I decide to not have any sexual content, that'll stay in this and any other future projects like it!
My original (and current) plan was to have sexual content in the game, once it's fleshed out enough as a game. I wanted it to be clearly seen as a hypnosis game before a porn game, basically. I do plan to include nsfw content in the game, but I'm interested in hearing what someone like you who (maybe) is more hesitant about that would think. I've planned on including a sort of way to "opt-out" before and during any sort of sexual content (in addition to the many other "opt-outs" that already exist lol), but beyond that, it is planned. If you're not interested in that, I won't be offended by you not following this project. However, if you have input as someone who's interested in the game through a non-sexual lens, I would absolutely love to hear it!
