If you play on PC, you'll be able to continue from your last save even if you delete 0.3 now. If you play on Android, you have to keep the current apk installed and overwrite it with 0.4
yeah im on pc, so if i delete 0.3 even 0.4 haven't released yet. i could still continue my last saves when 0.4 finally released? i get it now
yes. if you play on pc, your game files will be automatically saved at a different place. so you still have your saves if you delete the game
