Nice short little game! It wasn't bad on a keyboard, but I do wonder if it feels better on Android. I'm a flip-phone using Luddite, so I guess I'll never know, haha.
I do think the speed on the text reveals could be a little faster. If this was coupled with a larger story, and a little more variety, it could be pretty interesting. Almost like a visual novel or text adventure, but with a more active core game loop.
I also would have loved it if the "wrong ports" gave weird or awkward responses, as if your private message hit some confused other person. (I tried a few, and as far as I could see, it just resets you)
Good work!
