The older update before February it worked without lag.
Now, in february, it lags like hell.
Since new levels are added, I believe it is the cause of working levels in background, so please don't let levels hide in background, because I think the phone will load all that graphics and ruin fps.
Didn't tested all levels because of that much lag. Also, add version names like li.feb2020 to remind the current version.
Li means loot it, while feb2020 is the date.
