Helheim Hassle explains why the game doesn't have co-op

Perfectly Paranormal previously released Manual Samuel on the Switch, and their follow-up to that game is the upcoming
Helheim Hassle. While Manual Samuel allowed for co-op, Helheim Hassle does not. In an interview with Gamespew, creative lead Ozan Drøsdal explains why that is.

We talked about it and it would certainly be possible, however with static puzzles and never being in a position where you need to do several things at once, we didn’t see the point. But looking at it another way, puzzle platformers are co-op games by nature. Your friend can tell you to try flinging your leg on something while watching you play, and we feel that is co-op enough when solving puzzles. They don’t need to be in control of said leg as well.
