Description
Defiance: A Puzzle Shooter

Move your ship left and right while shooting the falling blocks with the correct color. Use up and down to change color.

The game speed constantly increases. Shooting same colored blocks in a row scores more points, and shooting 4 in a row reduces speed.

Good luck!

Controls are Joystick from either port, or Cursor + Space.

The Story Behind the game

The idea for this game came from a VIC-20 game called Avalanche that I saw online. That website says that a Plus/4 version of this game is coming soon... since 2012. I thought to myself: "I could code this!", and so I did. This game was written in about 5 afternoons in 2021 December (about 2 days for the game engine, 2 days for the music, and 1 day of debugging, polishing etc.). Big thanks to Chronos, gerliczer, KiCHY, Luca and siz for testing, ideas and general support!

The Music

The game comes with a new original composition. The nearly 7 minute long soundtrack features 3 voices on the TED! (Internally, there are 3 independently programmed channels, which are "mixed" to 2, plus the digi bass.) While there are several other musics which feature TED + digi sounds, playing melodic samples is always problematic (therefore usually drums are used). Playing digi while the TED is playing sounds causes the TED voices' volume to fluctuate. I've been experimenting with this for a while, and the best solution I found is featured here: a saw-wave digi bass. Playing a 3rd square wave caused big, audible jumps in the volume. Playing something like a triangle would cause the smallest "jumps", however, the resulting sound is very soft (in comparison to the TED voices). A saw wave is "perfect" however. The end result is: all 3 voices are clear (no "digi hiss"), volume control and playing noise is still possible, the bass is much lower than the default TED bass, rounding out the overall sound. Listen to it for yourself - I hope you like it!
