It's kind of weird to got 2 same haptic feedbacks while a quick click

Maybe it's a good idea to lower the up event's feedback intensity? Like, actuateActuationID = 1 for the up event?
I can do the PR.

It triggers two haptic feedbacks when tap down and tap up. These are not exactly same as like how taps on trackpad trigger these. The one triggered for tap up has slightly different pattern.

I know, its quite good with a longer click, tap-pause-for-a-while-up, but when you do a quick tap, will get a weird ta-ta.
I changed the up event’s feedback intensity to weaker the second ‘ta’, it works ok.

Okay, to me, it works even if it’s quick tap down and up. Probably, identifying each tap or key press and triggering timer to adjust intensity or wave form is the best solution but it may take some amount of work. Note this as enhancement and will work on it.

Great, looking forward..

Implemented a timer guard to not trigger haptic feedback too much frequently in a commit b2b4ad2.
Released HapticKey 0.3.1.
This should mitigate double feedbacks in a short period.

Great job!
