Hello there ! (This is a long comment)
I discovered your project by looking at the itch.io main page. I tested it and see how the app functions.
The idea of a chao garden app on smartphones is great, but for what I've seen with your app, in my opinion, it feels more like a demo rather than a complete app. Which is not a bad thing if it's under development, but considering that the app version is called "1.0", I saw a bunch of flaws that makes this app not finished.
In fact, I have so much stuff to talk about your app that I think it's best to show you a list of things that I'd like to see improved. But then again, this is your project, so you decide if you want to take my advice or not.
Other than that however, your app is quite good. The mini games are intuitive enough and there is a good list of items you can buy in the shop. I just think that this app should be better.
I also had curiosity with your app because this is on Android. And I'm searching for someone who can modify Android games, specifically using Java (it's about a Sonic game if you are curious). However, because I saw that you made this app using Unity, I don't think that you are the right person that I'm looking for. ^^'
That's basically all I have to say. Thanks for leaving a reply ! :3
