Nice app, potentially:
It needs an undo (for human errors in scoring—newsflash—people get drunk when playing darts) Also a nice chalkboard graphic perhaps so you can count rounds.
When you play the computer, it never throws in the black and never has a bounce out—no matter what level of experience you choose to play against.
How about a way to track players avatars/names and stats? Maybe a ladder/leaderboard?
