Brain Drain is one of those weird little Game Boy puzzle games that somehow sticks with you. It's got this creepy-cute vibe—you're solving these logic puzzles while this weird brain-in-a-jar character watches you. The puzzles start simple, but by level 3 you're already second-guessing every move.

What I like is how it doesn't hold your hand. No tutorials, just a quick "here's how blocks work" and boom—you're on your own. The music's oddly catchy too, in that repetitive Game Boy way where you don't realize you've been humming it for hours.

Definitely one of the more unique puzzle games from that era, even if the title screen looks like it was drawn in five minutes.
