I believe this app is normally paid, but when it was temporarily made free by the developer, I downloaded the game. As an adult, I've heard of coding, but I never had any idea of what it was or how to do it before playing this game.
The game has a low age minimum recommendation for gameplay, so I thought it would be fun to try out for myself. After finishing the game, I can say that I really enjoyed playing it! It was a valuable learning experience, and this app taught coding very well without taking away from the gaming experience.
The graphics are cute and kid-friendly, the mechanics are intuitive, and the instructions are clear and straightforward. Even though I'm not a child, it actually took me some thinking to get through certain levels as the game progressed, which support game's educational merit. This worthwhile app made me think critically and use deductive reasoning to logically solve puzzles that challenged me enough to complete each level without unreasonable difficulty.
The incorporated storyline makes the game feel more casual and subtly academic than a school lesson, which makes learning about coding much more enjoyable!
TL;DR: This child-friendly game teaches basic coding to people who want to experience how to code in an fun way.
P.S. The music is very exquisite and well-written for a kid's game! It is apparent that much thought and scrutiny was put into creating the aesthetic nuances of this amazing game, from designing adorable characters to making beautiful levels.
