For me your game works on Microsoft Edge and Brave, but not on Chrome.
I feel the ambiance was too loud at the beginning, and I wish there were names of the characters so I knew their names.

Pressing space restarts the game. That made me sad and confused.
I also clicked on the orange ship, which was mine, and it crashed the game, turning the screen completely dark.

After playing for a while, it just turns completely dark. I am very confused and sad, though I think it is really important you continue because your concept is cool, and the characters are cool. I like anime.

The fact you have your story in your comments is good, that makes me more interested in your game.

EDIT. Thank you @Martianitus the dark screen is not happening anymore. When I tried playing again.
