DPIN Shoot 'Em Up

A really basic shoot 'em up game made in GameMaker 1.2.

This was made based on the four hours a teacher spent introducing  us to the engine (since we haven't used it ever before). With that basic knowledge I changed most of mechanics to swift from a level-based gameplay to an infinite more infinity "arcade-ish" touch. 

It has two modes: Survival mode (with two difficulty levels available) and Turret mode. In Survival mode the player moves and rotates a spaceships. You can also shoot lots of bullets and to destroy the enemies (there are two types of them) in order to survive and increase your score. The Turret mode lets the player take control of four ships at the same time (that can't mode) and their objective is to protect the one on the center of the screen.

It obviously has it's issues (such as the spawning point of some enemies and some balancing issues), but it was a good prototype for the time.
