T-Rex by Raffaele Intorcia (commodore 64)

T-Rex

The game is entirely in Assembly for 6502 and runs on C64. It only uses two keys: space to start a new game and Return to skip.

The speed of the game increases to 100 and 200 points.

There are power-ups in the game but with the increased speed they become more difficult to collect. In addition, there is a jammer who could make it more difficult to overcome obstacles.

The techniques used in the game are:

* use of rasterbar for the background

* two-speed smooth scrolling

* sound effects
