AVSEQ (which we pronounce “A-V-Sekk”) is an audio-driven game based on an installation design by our chief programmer, Tom Betts, who multi-classes as an artist and musician. The idea behind the project was to create a challenging, abstract action game in which you link up atoms to obtain a high score. As you do that, however, you unlock the underlying structure to each level, which is a musical sequencer.
Ah, so now we’re getting to the origins of that strange name. AVSEQ = audio-visual sequencer. As you play through the pretty-looking visual atom-linking element of the game you also activate the sequencer grid, creating musical loops. This process is random, so each level playthrough will create a different loop, based on the grid of sounds you are able to unlock on that level. Each AVSEQ level has 2.2300745198530623×10^43 possible audio permutations, thats 22 tredecillion in total. No, honestly, that’s a real number, we looked it up.
