    Streets of Rage 2 Design Docs

    Make a Space Shooter for the Mega Drive!

    It’s time for another SGDK tutorial series! After doing a single player Pong game and an endless runner, it’s time to reach for the stars… and make a space shooter! Apart from things like scrolling and animating sprites, this new series will show you how to deal with multiple entities and their collisions, how to randomly generate backgrounds and more! This project builds upon the previous tutorials, so if you’re new to SGDK programming and have not done those yet, I highly recommend starting with Megapong.

This year I’m writing and submitting my MA thesis, meaning that I will have to do more stuff to make ends meet.
