I want to update game version from 0.2.4 to 0.2.6 but when i install the game it keep making new version of game not upgrade my version (i mean how to get my progress from old version to new ones. I use Android)

In each update changes are made to all maps, and this can cause certain events to change the way they behave, and therefore do not match the information saved in the previous version, so each new update must be played from the beginning.
