That’s a tricky question to answer! Between both the web and Playdate versions, I must have spent dozens of hours working on Skwish. But that was split across sporadic evenings and weekends over several years.
Yes, totally understand, most of us developers are in the same situation, it's hard to keep track of how many ours we put in this projects. Thanks a lot an congratulations, these are very good numbers for such a niche product as the Playdate is!
