An eartraining app inspired by the Tower Defense game and starcraft.
Monsters contain note(s) and clicking on them will play the note(s).
Guess the correct note(s) to kill the monster. You can use the keys 1~0, -, = to enter notes which corresponds to the notes C to B in sequence. (12 notes)
To win the game, have to keep the command center alive for 5 minutes.
To help with the game, after you accumulate 20 kills, you can use the nuclear bomb to wipe out everything on screen. Be cautious about using the nuclear bomb though -- you might want to save it for later when the real crisis comes.
