Just took a few hours to recreate the first puzzle from my iOS game, Nonoku, in Unity. Good timing as it was almost one year ago since it launched. You can play this version in your web browser here (opens in new window).
Nonoku is a tile based game where you have to reveal tiles by working out what colour they are. When you select a revealed tile it will show you how many unrevealed tiles of that colour there are in each direction. Games play out on a 10x10 grid and there can be up to four colours in a puzzle. Some of the later ones get quite tricky. The one here is from the tutorial.
Didn't encounter any major issues in getting the core game play implemented. In fact, it went even quicker than I'd hoped to get to this point. There would be plenty more to do in order to finish it out as a game but as I'd already solved most of the problems a year or two ago it felt like coming back to a really familiar project. Even though the original version was written in Objective-C in Xcode having a solution already in my head meant I could focus on getting it to a playable state.
I nearly didn't bother with the draggable cursor. I started with just being able to select a single tile but it becomes a huge pain to play. Adding it in meant a small re-write and a little more time spent than I was planning, but not by much. It's a little glitchy still but generally reliable and much better than only being able to fill one tile at a time.
The launch trailer for the original iOS version is below and you can find it in the app store here.
