Arrow keys. White - Dodge Blue - Stay still Orange - Move This is my Gaster Blaster Engine! Credit me if I let you use it. If you don't, I will come after you, and I'll get your project taken down. Anyways, I'll show you how to use it. Go inside the blaster sprite and use the custom blocks to spawn a blaster. Fill the empty boxes to set the properties of the blaster/blast.
I'm honestly impressed at myself for making this. Toby Fox for the Gaster Blaster sprite.
