I really like the concept and the atmosphere i'd be happy to play a more completed version as this one has a lot of minor issues and some game breaking
Mostly:
- leaving a read letter on the mat will cause a softlock as you will not be able to read any other letters
- for some reason i was able to get the true art stamp earlier? randomly when stamping a letter? I couldnt get it to happen again however
- not sure if intended but you can go from day 2 to day 7 if you make certain choices (ex: not stamping enough letters, mostly accepting/denying letters etc)
- the ui is very good for this game but the hitboxes are not, opening a letter and closing it requires multiple attempts so if i had to suggest something it would be maybe have a dedicated button to closing them on the top right?
- the tutorial could use some polish, a good chunk was spend trying to understand the game (especially on the first day)
- The purple stamp value looks more blue than purple and it took a bit to figure out
I dont know if this is your first jam but either way great job! excluding the issues mentioned this is one of my favorites in the jam a bit more polish and expanding (maybe longer days e.t.c) i think you have a very fun game here!
