Thanks for the feedback!
You did indeed solve "No way out?" in a much more complicated way than necessary, as the intended solution is also just a 1-mover. You're not the first one, though; for some reason, quite a few people we observed as they were playing also had a lot of trouble with this level. In the future, we want to either add a PAR score or a hard rotation cap (and maybe some connected gameplay mechanics) to encourage players to solve levels more deliberately.
The game does have more mechanics, but I suppose they are hidden too far away and a decent amount of players lose interest before they reach that point. We might introduce more complex mechanics earlier in a future update.
I see your point about the controls being a little clunky. Not a huge fan of swipe detection, to be honest, as I feel like more often than not, when games try to use swipes for 3D rotations, they fail. Maybe a combination of button presses could work.
We deliberately added a lot of easier levels early on to ease players in after getting a lot of feedback during the jam that the levels were too hard. I guess we might have overdone that a bit. In the end, I think that's also a question of target audience.
Better visual indication of walls is a good idea and on our to-do-list for the next update. More music is also on the to-do-list.
