The people who did the tutorial should be required to break one arm, and it's not just the developers of this game, and everyone who does not think about the standard things. Why is it so hard to disable sound/music?
please add feature buy, who buys a number of levels to 10/50/100. For example, if I have the 1443 level, click on buy 50(100), then bought 50(100), and 7(57) levels. Sorry for such a translation, it may be easier to show the algorithm. It was x=x+100, become x=x+(x%100) . it is very much easier life players.
If the user saves the game, after reloading the page shows only the detector. But it is possible to fix it after waiting until, until the AutoSave game, and restart the page, then everything comes back to normal. If the translation is bad, sorry, it's translator.
We've editted the tutorial per player request. Thanks for your feedback!
