challenges do not work as the items do not unlock. The rate you get candy is way too slow compared to how much everything costs it takes about 10 minutes to farm 100 candy. items cost 500-2500 characters cost 3000. that means you have to grind for 5 hours just to unlock a single character.
Until these issues are addressed no one should waste their money on this.
might be an issue where i have an existing demo save but there is no way to delete the data.
