I happily worked at a small shop that made clones of popular mobile games. I spent about 2 years maintaining and releasing new content for Match-3 games.

The team was great and I learned a lot from them.

I would typically respond to 'what do you do' with something like 'You know Candy Crush? Yeah? I don't work on that but I do work on a clone of it.'

It was nice to learn while working on a frivolous game. Felt weird thinking about who was spending money and how much, though.
