Aliens & Asteroids

Quick little game thing that I made in an attempt to get familiar with GameMaker. It mostly just takes from an existing GameMaker tutorial project, but I've added a couple new mechanics, including dynamic difficulty.

Shooting asteroids will grant you 50 points each. Large asteroids split into two smaller ones, which also grant 50 points on destruction. Every once in a while, a UFO will spawn that will occasionally fire lasers back at you, but grants 200 points when destroyed.

When destroying an alien UFO, collecting a power-up, when you miss a shot, and passively over time based on your score, your invisible "Danger" stat will increase slightly. As Danger increases, new aliens and asteroids will appear more frequently and move faster, aliens will fire quicker lasers more frequently, and fewer power-ups will appear. Danger can be decreased slightly while moving, destroying an asteroid, or letting a power-up go off-screen.

Right now, the game is pretty bare-bones. I'd like to add more challenges and stuff in the future, and at the moment high scores are not saved when closing the game or even exiting to the menu... we'll see whether or not I ever update this.
