Thing Trunk is an independent gamedev studio founded by 3 guys, who are known for engineering their games to their fullest: Maciej Biedrzycki (co-founder of Codeminion), Konstanty Kalicki, and Filip Starzyński (founders of Twinbottles).
Having created many successful games at their previous companies (most notably Saqqarah, Magic Match, Brunhilda, Phantasmat) and a few unintended flops (let's not put names here) they quickly became disappointed with the miring trends in the casual games market. They scrapped their former brands and together founded Thing Trunk to focus solely on the ambitious Return 2 Games idea.
