I know very little about Thai culture but adding traditional elements to the story is a nice touch.
The art style was cute, I managed to get 1 good ending (I liked the puzzle behind the box) and 1 bad ending.
The english was a bit rough, but I still was able to understand everything (as a non-native english speaker myself, I can assure you that you'll only improve from here on, so keep it up!). All in all, good job
Also, Suwanan was my favorite character, I hope I didn't misspell the name
