My name is Nick and i`m an alcoholic. Uh, sorry :) Wrong channel! I`m a developer and lead of small indie studio named AurumDust. This year we had released our first game Ash of Gods (https://connect.unity.com/p/games-ash-of-gods). It was probably the most hard and complex thing i ever do as game developer. If you have any question about complex and huge 2d games in Unity please PM. I would love to help and share my experience.
