How about an ultra rare Sir Robin easter egg that has max speed and moves knightwise, and if you kill it you get 1000 coins or some achievement?

new enemy type idea: gun
1st gun: gosper glider gun

how it works:
periodically emits gliders, at 5 ticks per second.
health is that of the turtle.

how it enters:
it enters via glider synthesis animation, the gliders should be really fast, and invulnerable.
if glider synthesis is too much, then i guess just a white flash should be enough to hide the gun while it’s being placed.

new enemy type idea: puffer
1st puffer: blinker puffer 1

like a spaceship, but the special ability is lay blinker.
blinkers have the health of a glider, and moves at the same framerate as the puffer.

also here’s a game review

things i like:
prices are nice, not too low, not too high
game is fun
there’s enough variety in enemies
difficulty progression is great

things i slightly don’t like
because of the curved path the ship takes, i am unable to shoot the edge, when i really need to
fever mode doesn’t make me invulnerable like i think it should
player controlled ships aren’t game of life patterns like the queen bee or something

things i would like
a bonus event that only pops once a month, if you play the event, you play in the zebra stripes agar. might be too complex though.

rakes, puffers, and guns.

You should add rakes

if your gonna add puffers, add still lifes we can lay down in fever mode
