Thing Trunk is a small game development studio and a creative team behind Return 2 Games - a series of original mid-core games inspired by the golden days of PC gaming. The first installment, Book of Demons, was a smash hit on Steam.


The the studio was 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 the 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.

Revealing your game can be a nightmare - an emotional postmortem of Book of Demons announcement
Imagine for a moment that one day in your life you had an idea. The greatest idea of your life. And then suddenly, after a few years of hard, sometimes impossible work, you realize that you are quite close and you gain confidence in yourself. There’s just one problem – the last obstacle in your way is marketing, something different from the ones you tackled. Something you dreaded for all these years and foolishly hoped it wouldn’t come. It’s just like an almost impossible-to-beat end boss in a game and you just have one heart left…
Defining Mid-core games and why they matter

Return 2 Games Music Theme - Live orchestra on an indie budget
So basically, you pay a 100 bucks, and get a 7 minute professional recording of a live orchestra playing your music. As you can probably guess, we were instantly sold on the idea. We really didn’t know what to expect, but we wanted to try it out.
