I'm a software developer from the UK. I sometimes make games in my free time. My first moderate success was a Boulderdash type game called Gems'n'Rocks, which I released to Intel's AppUp store in 2011. It had several thousand downloads and achieved fairly high ratings.
A couple of years later I released Minefield to the Ubuntu Software Centre, where it rose to the top of the Puzzles category with five 5* reviews. It remained at the top until the software centre was eventually discontinued.
My latest game is by far the most ambitious, and without doubt the best thing I've ever made. It's called Pro Office Calculator and is available here at itch.io and from its official website http://proofficecalculator.com.
