Write to contact@amcrafts.in and tell us your device, your Android version, and what happened. If the game is installed, the version is on the About screen. We read every message.
Progress lives on the phone. If you created an account, it is also on our server: sign in on the Cloud Save screen and it comes back. A guest save is on that phone only, and reinstalling the game starts it over — that is why the game offers an account.
In the game: Cloud Save → Delete account. Without the game, open the deletion page and enter the e-mail address and password of the account. Either way it is immediate and cannot be undone. Progress kept on the phone itself is not affected; uninstalling the game removes that.
Every one of the 500 campaign levels is checked by a solver that plays the real game before it ships, so each is winnable. If one still will not fall, tell us the level number and we will look at it.
Rewards are granted when a level, mission or season step completes. If a payout looks wrong, send us the level or mission and roughly when you played it.
The campaign, the boss levels, Nova Rush, Arcade, Relax and the daily and weekly challenges all work with no connection at all. Only cloud save and the leaderboards need one. If those say "no connection" while everything else is fine, the fault is at our end and it is worth telling us.
Send it to contact@amcrafts.in with enough detail to reproduce it. Please do not test against other players' accounts. We will confirm we received it.
