Wow, the difficulty increase very fast! I didn't success Level3 ^^
Nice concept, would be good to have it release on Android too!
Someway I feel like the laser doesn't fire straight when the ship is spinning.
It seems it's because the laser starts from the ship center, so at the time it appears (when it's not hidden by the ship) the ship already have rotated to another direction.
Maybe it's just me, but I think it would be more comfortable if the laser starts already from the front of the ship.
