Awesome game, thank you! And it looks like even the ZX Spectrum Next (a beefed-up version of the classic British computer) community has noticed it: https://www.facebook.com/groups/specnext/permalink/1412682115755771/ People in the comments there started even wondering what would it take to port satryn to this retro computer...
Well, there are some interesting efforts to bring indie games to retro hardware, check out for instance Limbo for Commodore 64 or Cave Story for Sega Genesis. A floppy or cartridge with satryn could really look interesting on a shelf. :)
