Mail Time
Short and cute.
You explore a small open world and backtrack a lot delivering letters between the characters you meet. Sounds tedious, and it could have been so were the game any longer.
The delight is due to cheery and colorful world and the lighthearted, funny conversations.
Perhaps less delightful is that the world is not that interesting to explore. There are, for example, a few areas that are begging for more things to do. Maybe development was cut short? Also, as cute as the conversations are, they can drag on a bit too much. Again, if this game were any longer it would not have worked so well.
Mail Time delivers (pun intended!) an enjoyable couple of hours. I recommend it.
