There hasn't been i new public update release for android for a while now.
Whenever we do an update for any of our games we release it for PC, Mac and Android at the same time so all platforms have the same version. The Android public release of the game is the same version as the PC and Mac versions.
There is a newer version exclusively available to patrons (which is released on all platforms) https://www.patreon.com/begrove
