Requires a lot of precision, which can be fun for some- the movement schemes makes it so you're always going towards the enemies, so weaving around sounds like the aim of the game, " spinning around them to win "?
At the time of writing ( 24 hour period of bug fixing not elapsed), the game does have a couple glitches that make it sadly unplayable on my browser. (Perhaps caused by me remapping the fire button to Left Click?) Clicking on the player ship resets the game ( affected by your own shots perhaps ), and clicking near the center kept sending me back to the main menu.
Good job for putting in an entry regardless, I hope you had fun doing the jam!
