Mouse only. Which also means you can use it on mobile. Why you'd need a recreation of Fruit Ninja on mobile is beyond me, though.
Thank you to HalfBrick Studios for the original Fruit Ninja. All code is by me. 99% of assets are from HalfBrick Studios. Please alert me of any bugs. This might be updated to add Blades, but I can't promise that, if I do it will be a separate V2 project with more stuff. I did want to add Blades, but once I shared it I thought I might as well keep it up.
