Hey, hello!
Songs in the game are mostly original songs, except for "The Builder", that's a song in public domain.
But you can listen the title menu music and Lenin's theme on SoundCloud! Thanks!
Hey, now there's a crowdfunding campaign for the project! If you liked it, please, consider back the game on Catarse! Here it's: https://www.catarse.me/lenin_the_lion. Thanks a lot for your support!
