A very solid Shoot Em Up, especially for emulating a Gameboy style. Aside from the lack of colour making it difficult to tell certain elements apart (which of course you can’t really do anything about on the Gameboy), my only real issues with the game are that a lot of the difficulty did come from the player’s larger than normal hitbox and the lack of telegraphing on enemy movement and boss attacks. It was also a bit difficult to tell when the player actually took damage, since the only feedback appears to be the flashing of the shield/ship bars (a unique sound would’ve been handy).
