Binary Land is a game focused on a simple but weird premise. There's this pair of penguins, and your goal is to have both of them touch that caged heart. But you control both at the same time, with their horizontal movement mirrored. Trying to use the same inputs to solve two different mazes simultaneously will either give you a headache or be a really compelling challenge, and for me at least, it's the latter. This is one of the few Famicom games that I feel like I can still call a hidden gem.
