The game is super cute and was a lot of fun :D
Most of the minor issues I wanted to mention were already mentioned, but I have a few more^^
The first time you open the character menu (Esc) ingame, it takes a bit to generate/ load. Maybe you can preload it upon starting/Loading a game? :D
Also the Depth of Field for post processing seems to only be "focused" in an area behind the character instead of 50:50 in front of and behind. (especially noticable with NPCs.)
Also noticed that the paper airplane card respawned when I reentered that room later^^
Good luck with further development :D
