This is a tribute to Psychedelia by Jeff Minter. It's adapted from the version included as a sub-game in Batalyx.
It turns Psychedelia into a game of sorts. Filling the screen with as few moves as possible maximizes your points. There are infinite levels - so you never lose and you never die.
There are some deliberately tricky levels, but on the whole you can sit back and enjoy filling the screen with glowing patterns.
User the arrow keys to move around and Ctrl for 'Fire'.
On Ubuntu you can do:
sudo apt install 64tass viceTo compile and run it do:
$ makeThe compiled game is written to the bin folder.
To just compile the game and get a binary (psyii.prg) do:
$ make psyii.prg
