Made it almost to a minute. Nice song choice and charming visuals. But feels a bit too simple for a 7 day jam. Lot of scope for additional story elements, enemy types or modifiers. Right now its feels like a good base for a roguelike.
Immediate suggestions would be to make sure the gf doesn't drift too much to the border since then the player has too less time to react to seagulls from that side. Also the dead seagulls motions seems a bit random an it is especially unfair that a dead seagull can hit the gf.
