One of my more earlier and simple games, but pretty complete. YES2 was made for mobile devices and released around 2015 on Google Play, IOS and Amazon stores. The game consisted in 4 games in 1. they are simple games with simple graphics, but the type of game you try, and retry, again and again... I believe each game had 5 worlds with 10 levels in each. Learned a lot about UI and scene management with this game.
