The SIphonopolis sountrack has just been released: https://store.steampowered.com/app/2127250 Just like the game's graphics, the music originates from several old projects. Some of the tracks have been remixed and/or extended. A few small improvements to the game have been added: [list] [*]Reworked the attack of the third mid-boss in level 47. [*]Machine gun hazards now make a flashing animation a second before shooting. [/list] And finally, an easter egg of my previous game "Me and My Eldritch Parasite" has been added. Good luck finding it.
