Check out my Laser Defender game! It has different sprites, sounds and music, and two enemy types. It also has some extra particles that’s (meant to) resemble asteroids and close up stars. The thing I’m most pleased with is that it remains on the game screen when you die. And for the record put the star particles on the start screen before I got to that lecture.
I’m still using version 4.7.2 so it won’t work in Chrome. Controls are WASD to move and LMB to shoot.
Big thanks to @Joao_Dalvi for responding when I needed help.
