This is a helicopter game written in AVR assembly for an ATTiny13A connected to a Nokia 3310 LCD and 1 button. Made for the fun of the challenge to fit a graphical game into 1 KB code space and 64 bytes of RAM while running at 1 MHz. Also wanted to do something that used all

High scores are saved in EEPROM so you can compete to be the best.

Some of the code might be interesting to look at:

lib_lcd - Shows the magic numbers needed to make the cheap 3310 LCD work. Implements software SPI.
lib_disphex - Very simple printing of hexadecimal numbers in assembly code.
lib_eeprom - Simple EEPROM control.

The level generation program is a Processing sketch that outputs a source file representing a level for the game.
