Hello friends, I'm the designer and artist on the project. My partner @willmallouk did the coding. Together it took is a little over a year to make the game in our spare time while working at other studios, that was 5 years ago. Since then we've been updating it regularly and it's had over 3 million downloads across all versions and platforms. If anyone here on product hunt would like a promo code for the premium version on iOS- just ask, I'd be happy to get you one :).
