Okay, I'm a big fan of pixel art and chiptune music, which influences the score I gave. It's hard for me appreciate a game where all the sprites and backgrounds are hand drawn. This takes me back to when I was a kid and Nintendo was a house hold term, back to the days when we talked about who got a love letter in their locker at school. There is a great sense of mystery and suspense as soon as the letter is found, and the excitement swells as you find a secret place to read the letter. No matter how many times I play it, it always feels like I'm reading the letter for the first time. The thrill of being found out makes it feel like I really am at school. It's interesting, yet a little frustrating, that the other students chase you around the hall. Although, can't they see what you're doing from a few feet away? The music is very appropriate to the situation in the game. Very nice.
There are a few things I'd change if I could program. I want to start the game much sooner than the text windows allow. I wish I could press a button and skip to the objective. I also didn't know that I could use the keyboard to move instead of the mouse until I read the description. Something like that should be explained in the game. I think that the other students should be on to you from a slightly greater distance. They aren't blind. There should also be other kind of students; those who take a great deal of interest in you and others who don't care. I see this as an introduction to the rest of a game that isn't there. I would love to see what happens afterward.
I have fun every time I play this. You get 5 stars!!
