Snake renders using ANSI escape codes via debug_putchar syscall, bypassing the VirtIO GPU (which has a QEMU 11.x legacy MMIO bug where transfer_to_host_2d succeeds but doesn't transfer data). Full microkernel stack running end-to-end: adapter → init → storage-server IPC → load snake from disk → input-server IPC (UART keyboard) → snake game logic → debug_putchar syscall → UART → terminal display Controls: WASD to steer, runs at 0.2s tick rate. Green O=head, o=body, red @=food, #=border.
