Short answer: Holy fuck.
This is a game that is shamelessly and unabashedly embracing its theme and running with it - and as a longtime hypnokink lover I was absolutely head over heels from the start. The sheer variety of different tropes from the genre was a feast to experience - snaps, clickers, bondage, visual distortions, visors, metronome, drugs, pocket watches, petplay... My god. The multitude of different spirals for the different sectors was a very nice touch as well, and spoke to the labour of love this is.
Gameplay wise my favorite part was: being savvy with genre tropes? Not enough to save you from bad ends. It was really fun to occupy that space of "trying, and failing anyway" in a more sincere way than any other hypno media I've come across in memory. Additionally, the binaurals getting louder as you got closer to a bad end was a great touch - it was absolutely worth getting the headphones out for this.
Unfortunately I did run into bugs - the binaurals not stopping when I reloaded and then breaking when i refreshed the page meant that downloading the standalone version was an inevitability. (Thank god for the save system). More tragically, I did get hardlocked in my first run of the game - all reactions I could take to escape/defeat Iana errored out being unable to find a room. Totally worth the effort to restart and finish the game, but still a pain!
Frankly after playing through this, I'm even more flattered by your kind words on my own entry (and extra sad I never got to implement the hypno character that was intended in it, hah!). Your writing is captivating , this game fully made me stay up way too late on a weeknight, and I'm definitely going to be following you post jam to see what you get up to.
