Hi this is Tray! Here's my comments:
A like: I love the aesthetic and concept of the game, it's really cute and creative. The idea of sorting emails is unexpectedly fun when put into game format.
A wish: I think if there was way more time for the production of the game, the emails could possibly be slower paced but there could also be other tasks that you have to complete on your "computer" (so more tasks but at a slower speed), but that's of course a way bigger scope than the current concept.
A wonder: I remember your team discussing a different idea (more educational). What inspired the concept change?
