Always nice to see another GBA game in this jam. :)
The idea is certainly a nice take on the theme and the snake AI does usually a good job at not killing itself, making it actually fun to try to trick it. Graphics are fairly simple, but that makes them at least clearly visible on the small washed out screens these devices have, so still a plus.
One slightly annoying problem I ran across, no idea if it is specific to real hardware, is that the game sometimes crashes when the snake dies, showing a screen claiming it ran out of sprites for displaying text. Not the win screen I was expecting, but hey, GBA development can be tricky at times, especially under time constraints.
