Hey Cam thanks so much for your heart warming comment!
You are right, the bullet is a little small and the laser can get you even when you think you are covered. I will fix that.
I've been thinking of mapping R to restart but completely forgot! I shall fix that as well.
Do you mind sharing a screenshot or describe to me when the sticking happens? That's no bueno. The composite tilemap collider wasn't working for me so it may be that there are gaps between the tiles or something...
My code is a complete hodgepodge - please go easy on me! XD
Cheers!
