LD42 WebGL - Johnny's Flipbook Space Adventure

Johnny is not allowed to play on the computer right now, so he decided to play his favorite space shooter on paper. Johnny has created a flipbook of his adventure fighting aliens, complete with sound effects he created. Every so often, his little brother tears some of the paper so Johnny's spaceship has less and less space to fly. This is my entry for Ludum Dare 42's theme "Running Out of Space". Controls: A/D or Left/Right Arrow Keys to rotate ship. W or Up Arrow Key to thrust. Spacebar to fire bullets.
