This homemade version of Galaga was my final project for a CS class I took in 2012. I created and implemented the physics engine myself using timer events and linear algebra. The artwork was taken from google searches and edited in GIMP. Music by Nosaj Thing.
Note: The game is barely stable. I think it contains a lot of experimental features that I never completed or removed, so don't expect much. I worked on it for a few weeks, then never touched it again.
