Great app and customer service

My son loves these math apps because he feels like he is playing a video game while learning.
Initially I had trouble with the app launching, but after emailing the developer they promptly fixed the problem and when I relaunched the app it was working great! I am so happy with their customer service and how quickly they fixed the issue.

This deserves 0 stars because you have to pay just to go to a higher level and you can’t change skins the only thing you can do is get the highest bubbles and to not run out even tho this game is trash it kind of picked up my math skills a little . So thanks for that game

Edit it ask me to change me review and that it’s a “children game “ well I am a child and I don’t ask for money so no I won’t change it
