I really love the concept behind this!
Had a minor bug with one customer who wanted a "creature" and don't forget "cicada" and I gave what I initially thought was the painting but then had like a mini 'freeze' and then they wouldn't collect the painting anymore
However, I really love the concept in general and it's really fun! I like how you even prepared a storage facility for players to organize their items!
Had a bit of an issue with the labeling system however! I found it too difficult to scroll through everything especially when I realized it wasn't alphabetical. Unless it's part of the game mechanics, it's fine as well!
Overall, it sounds like a game I'd definitely try when polished!:) Well done!
