A cute little game that is programmed well, I liked it! Cute premise, cute style. I had two major feedback notes while playing:

I had a little issue opening and closing menus at times, they don't close if you try to change areas with them still open and sometimes don't let you switch areas, just little bugs like that that probably aren't hard to remove

For the mystery, fundamentally you only really need the classroom note to solve it, because only one character has an "E" as the second letter in their name, revealing who signed the note by just that; more similarly named characters would alleviate that. It would be more engaging if the miscellaneous clues added to the mystery, but I did like the robot sidequest, it was cute :)

Cool game. I like how you turned a plot so simple into an actual mystery, and I enjoyed playing it all the way. I guess once you find the culprit it becomes sort of obvious but maybe it would be good to add a short explanation at the end. Overall it was a fun experience, though. Thanks very much!

Very cute mystery. I especially liked the little touches of sound effects added when you interacted with certain things - it made the world feel very lived in, which supported the art style and general vibe. The music was solid as well! My one complaint is that some of the clues were a little opaque, for me at least; I was able to decipher the message with normal cryptography, so it didn't really matter, but the pictures didn't make a lot of sense to me just the same. But overall, you guys did a really nice job on this one!
