I finally had some free time to make something fun and decided to write a new game for the Attiny85 ssd1306 keychain. I reused the sleep, display and interrupts code from the “Breakout” game I created a while ago.
This time I wanted a more addictive game. The game had to be playable using just the two buttons. I thought a racing game might be a good choice but the landscape screen is more suitable for a side-scroller. So I settled for an obstacle avoiding side scroller. Similar games include the recent Flappy Bird, Nyan Cat and many variations of the Helicopter game.
The flying saucer is propelled with the left button while the right button is used to shoot through force fields. The game gets harder as you play:
This is a 500 RGB pixels ceiling I made, the project was done in March 2013 and has been working non stop every day since then. The ceiling is installed in the kids department of The Golden Boot shoe shop.
