I'm working on version 50 for Patreon this month.
I honestly don't know the answer to that question. You'll have to time one of your runs and let us know.
As far as I'm concerned my friend Speedrun it in about 9 hours and 43 minutes without interruptions
it actually takes less for the public build bit the patron
build took longer for him because you can only play for so long before the code kills itself he had to restart 6 times
