This was fun! I think I found all the endings (assuming there were four). I saved the "no romance" playthrough until the end, and was expecting it to be kind of awkward picking all the unsociable responses, but I actually appreciate that even in that scenario, the interaction feels friendly. The no romance ending does a pretty good job of subverting the expectation that starting a relationship is the win state, which is nice. I'd pretty much never consider speed dating in real life, but this game's helped me understand why some people would, which is also cool.
I'm trying to come up with some constructive criticism, but there's honestly not much that comes to mind. More #content would always be good, of course, but in some ways it's nice that the game is short enough to accommodate several fast playthroughs. Oh wait, I do have a criticism: socks are a cool gift for hip young people okay? Also, sharks are gentle ocean friends that wouldn't harm a puppy.
