This is a tough one. The main culprit here is that trademwark law forces the trademark owner into an active defense posture to avoid losing the trademwark. This is very different from patents or copyright. So, in a way, IKEA was forced to write that nasty letter to the developer. Still, it's obvious fromo the published game footage that the developer was trying to walk a line between referencing IKEA and calling them out directly.
I kind of wish that lawyers could settle these things more amicably than by opening with outright threats. The game is clearly taking SCP 3008 as its inspiration and that is a a quite satirical horror story take on IKEA stores. A part of me wishes that companies would be a bit more relaxed about obviously comedic or satirical uses of their identity. What would IKEA lose by approaching the developers in a more supportive manner initially? Say, by offering some more constructive suggestions to steer them away from the particular elements they take offense at.
