In 2022, an Easter egg was discovered after one of the game's developers hinted at its existence in the game's Discord fan server. In the Ungard Mines level, when you come to the big bridge, you can turn to the left to find two bags of gold. Pick up the first bag but leave the second bag alone, and then carefully walk to the end of each of the four diagonal support beams holding up the bridge. Afterwards, on the opposite end of the bridge, walk to the end of the carved out rock path on the left side and stand in the corner of the rock wall. If done correctly, the "Use" prompt should appear. After triggering it, you can turn around and see a developer credit written in magical colored lights hanging over the abyss: "J.A WAS HERE". This is in reference to one of the game's designers Jens Anderssen.
