Reverse-Tamagotchi. This is what drove me to try this game. After all, being around in the era of Tamagotchi and such devices, reversing the roles was an interesting concept to me. This game pulls it off, as well as throwing in a taste of dating-sim for a great experience.
The graphics style is fantastic, with a hand-drawn sort of feel to it. Sounds are great, although a little more music would've helped a little. Controls and game play are both pretty straight forward. I got the love ending (I think...), so I can't wait to see how the other endings play out.
I think you pulled off the reverse-Tamagotchi concept in great fashion. Nice job!
