Finally got it working thanks to the comments on here - really cute game, love the sheer variety of options you can find. Elements like the radio, sticky notes, and the background character just working away make it really homely and cute.
Agree with other comments that lack of hints is a main sticking point - you get to times where it’s less exploration and more systematically working through until something works. Extra rough when a large number of options are hidden behind blocks that aren’t intuitive to unlock (“trait” is a big one) - if I hadn’t had access to the cheat sheet you’d uploaded, I wouldn’t have stuck it out to 100%.
For specific interactions, marine being available from the beginning but having no combinations was a bit feels-bad. Tying genitals/chest to gender also didn’t feel great - this game has a really great setup to make those traits separated from the concept of gender entirely!
Will be interesting to see this fleshed out more!
