Did You Find Headlander’s Rocket League and Psychonauts Easter Eggs?

Stacking

Headlander also contains a reference to one of Double Fine’s earlier titles, Stacking. The game is about solving puzzles by jumping into Matryoshka dolls of different people with different powers. Much like Headlander, it’s an inspired game with a brilliant aesthetic. You can spot the games protagonist just behind Headlander in one of the secret tape recording rooms found in the game.
