BetaVersion: Sound lags every 1-2 seconds.
v1.61, Debian Stretch x64, alsa, integrated Realtek soundcard
JudasIscariot: Does this happen with version 1.63 that we uploaded today? There is a patch for you in your account, please let us know if it solves your issue with the sound :)
There were sound issues on Mint 17.2 64-bit too. It seems they're fixed in this new version.
The previous installer included the required 32-bit libraries. The new one needs to write some libraries manually (such as libSDL2-2.0.so.0) to the games /lib directory.
For users who don't already have them and can find only the 64-bit version in the repositories, download them from:
https://www.debian.org/distrib/packages Open the .deb package as an archive and extract the shared objects. Then copy or move them to the game's /lib directory.
