Lagging
The game lags randomly, and gets worse with worlds. In world 3, some jumps requring timing are almost impossible the first times without losing life, because the game starts to lag and runs «choppy». The game is played on a new iPhone XS 256 GB, with no other apps in the background. Further, the game is full of commercials with no possibility to remove them (by e.g. in-app purchase), and it constantly asks to use personal information for targetted advertising, and does not remember the settings if you say no. Other than that, a cool game, but with too many performance bugs when you approach final worlds.
