Yuri and Cyberpunk? No way I'm gonna skip this, heading over to KS after writing this comment. :)
The art is.. hmm, peculiar. Looks very hand-drawn, both backgrounds and characters. Have only run the demo briefly so far though.
Just one thing: Packaging the game as a .zip file doesn't preserve POSIX permissions. So the game cannot be run as-is on Linux. You have to change the permissions on a few files in the game folders after unpacking:
$ chmod u+x ./lib/linux-x86_64/Synergia ./lib/linux-i686/Synergia
$ chmod u+x ./Synergia.sh
Packaging it as .tar.gz or .tar.bz2 would fix that issue, but I guess that's a bit more inconvenient for Windows users.
I think Ren'Py should support packaging the game for each platform individually though? If true, maybe that'd do the job (Making a .zip for Windows, and something like a .tar.gz for Linux).
Anyway, it's not a big deal, just wanted to mention it. ;)
Alright, time to back that VN! :)
