I tried it, but it’s a different game then. With a timer, you feel a sense of urgency and can’t be as precise. The first version didn’t have a “repeat level” button, so you had to start again from the beginning ;p That was too difficult - more like permadeath.
In the end, I can also see potential for a non-themed version, but in my humble opinion, the timer is what gives it that arcade feel.
