Hello, follow the steps bellow :
1. Click on download button (to download the game's archive, which contains Android Apk game versions and PC game)
2. Extract the .rar archive (7zip is good on PC and android via PlayStore. Install the app, then find the downloaded archive, choose open with, select 7zip)
3. Install the .apk file (x64 is recommended, if it doesn't work or crashes or lags then try installing other apk files)
4. Enjoy
For the next update i'll switch to zip, should be easier to extract.
If there are any issues feel free to contact me (comments in here or email to me)
