The initial release of Vanish5+ is now available for download over at Itch.io and Vogons.
This is my submission for the DOS Games End of Year Jam 2023.
Update 2023-12-29: For those of you running the game on real hardware, I noticed during testing that MIDI/OPL output didn't work properly on a real SB16 (with OPL-3 chip) due to the register write timings. This is now fixed in v2.
