About Thing Trunk


Thing Trunk is a small game development studio based in Warsaw, Poland. The core team is comprised of seven dedicated developers. The 3 founders ― Filip Starzyński, Konstanty Kalicki, and Maciej Biedrzycki ― are casual game industry veterans who (despite a level of success) became disappointed with the miring trends in the market and scrapped their former brands (Codeminon and Twinbottles) to focus solely on the ambitious Return 2 Games idea. Since then, they have been busy trying to prove that making the high-quality games is possible with a small but experienced team with lots of passion.
