It being a Game Boy Advance game is a great detail! The concept is pretty fun to play, but I wish there were more ways to force the snake in a direction, though baiting him into eating you is a great concept on its own. Audio would've been fun, but I can imagine how difficult that would be during a Game Jam on a GBA emulator. The variation options were fun, but overall, a higher base speed would've made the game more engaging. But in the end, great job!
