I like the looks of it, however, there are some stuff that differ from the original Zelda GBC games, I'm not sure if it is your intention to do that way or not, but still:
1. Type of Letter in A, S and D. OMG, Times New Roman totally sucks... >_>
2. Bigger hearts.
3. More space between the rupee counter and the D slot...
And: I'm waiting for a demo ;D
