The game seemed too easy in my opinion. Maybe it would've been different if I was playing with a second player, but for me the game was mostly just move one character to the switch, and then move the other character to the next switch, and then just repeat until you get into the end, there wasn't much of a challenge. The part at the end where you use the rail robot as a light was much more of a challenge for me, I wish the game made use of that more.
