The art is superb, and I really like the SFX with this game. This game definitely gave me the "Check your email" anxiety lol.
My two biggest thing was that the instructions were more in the description than in the game so when I was in the game, I felt like I jumped in too fast. The second is that I couldn't really tell when I was doing something right at first, and afterwards didn't feel rewarded for successfully navigating an email.
