Not sure on the original, but I spent about a year working on it on weekends here and there. Hard to find time with full time work and other projects mixed in.

Not sure on the original, but I spent about a year working on it on weekends here and there. Hard to find time with full time work and other projects mixed in. I would say it was around 100 hours of work in total. The majority of the was done within a couple weeks but there were a lot of performance tweaks and bugs to fix.
