When I first tried playing the game on an emulator, I found it pretty much impossible to play using a mouse. I found this hack when looking for a solution, and it works pretty much perfectly.

You can use A, Y, Up or Down instead of tapping, and B or Left instead of flicking. You can also use L and R to slide up and down, which is useful for minigames like Love Lizards and Love Lab.

One very minor annoyance is that you still have to manually tap the screen to progress through dialog screens, like at the beginning of a practice or after you’ve finished a minigame. This is a very insignificant issue however, and doesn’t affect overall gameplay in any way.

This is a perfect hack, and it made my experience with this game much more enjoyable than it would have been otherwise.
