I’d say so, yes. Coordinating two players to do their things in the right order and getting the timing right requires a lot more thought. I did finish the single-player mode and there was one near the end that had me thinking for a bit, but there was nothing as challenging as what’s in the co-op mode.
I was playing it with my kid as well and we really enjoyed it, even though it was me just directing them what to do for a lot of it.
I think I encountered one glitch in single player: there were three lens cubes in the room that I needed to use, and at one point I just lost one. It’s possible it got fired into a dark corner of the room and I didn’t see it, but I think it glitched away. Not too annoying since I just reloaded the level to do it again.
