so it can actually read sm files? that's awesome!
i have a list of suggestions:
- be able to change the key bindings to any keys
- be able to turn playfield upside down
- hit effects ( you can use default animations )
- flawless, perfect, etc. popup when you hit a note
- show combo
- result screen
also I can make better arrow sprites for you ( and other graphics you may need for this )
