wow
that was great but there were a few problems
1: Sometimes if you pressed an arrow for a double bit you could get a perfect on the first arrow but at the same time the 2ns arrow would count as an early.
2: During a long note if you let go early you lose the point for the whole riff not just the bit you missed.
3: Try to stay away from the parts where you have to press 2 arrows at once. They can be really almost impossible at those speeds.
And Finaly 4: Maybe next time make it so that earlys and lates dont break your combo.
Apart from that the game was great. If you make another one i would love to see use of the spce bar mayby??? Oh and mayby a mode where you can pick one of 3 instruments and just press keys to do random riffs or something.
