My first shooting arcade game!

hey guys, I made shooting game for the first time forever.

It is multiple player games and it has story on it.
which is
(there is a fish that has special and true love story under the water. It named, Ninespine stickleback. Female Ninespine stickleback leave male fish alone after lay eggs. Therefore male fish has to care about the eggs all by himself. Male fish doesn't eat and sleep until the eggs are hatched. Normally, It takes 8 to 15 days. He is willing to fight against other creatures which want to eat his eggs.

Eat or be eaten, survive from the nature.)

you can download the game from these sites.
