Bird communism!
The writing is fantastic - how did you even pull this level of writing off in 3 days!?!? I was pleasantly surprised to see that there was indeed a good ending for everyone involved, and that you could genuinely befriend Utsuho - I was worried that you wouldn't be able to, or that it would be an up-to-chance sort of thing.
The chance decisions (talking to the chickens, scaring Aya, etc.) don't really seem to affect anything, and I haven't found any ways to raise my skill levels. Maybe there wasn't any time to implement the non-linear/skill aspects further, which is understandable. Still, it didn't affect my experience much, if at all. I really enjoyed reading and playing this!
Good work on the game!
