I want to add a list of achievements (the checklist you described) that tracks if you've seen every major part of the game. I don't want to implement that yet until the game is more finalized - there are still so many side paths I plan to add, it would be weird to have a checklist saying everything is done when "everything" isn't actually everything, yet. Don't spend too much time looking for the blue haired girl though, it's a pure rng 1/100 chance to appear and she has one sentence of dialog. Too small an easter egg to be worth it.
Thank you for the feedback on pokemon cries, for 1.3 I'll do a thorough check and rebalance or replace anything that's fucked up.
As for the next update, I'm going to get at least one more out before the end of the year.
