This game is pretty cool. You may be done with this project, but there are something I want to talk about.
Firstly when I clicked the like of this game to Playstore, it doesn't seems to be available.
Second, when you pet chao, the chao sprite is yawning, not the one which chao is being pet. Perhaps there's reason you did it like this. Besides that, the behavior is a little bit different, but I think it's fine. Perhaps there sould be more behavoir features or smth, idk, also more of chao's voice. Perhaps there's a few glitch, but does not harm the game badly.
Then maybe a little strange, but in TCG, chao sometimes talk a little, so perhaps put this feature?
Also the background music in garden isn't what I'd expect. Perhaps should be be like neutral garden or from TCG.
To make things cool perhaps clothing and accesories for chao to wear should be in this game.
And then the pause button and screen. Should be having stuff like settings or quit or maybe go to title screen
Lastly, at the spring jumping game thingy, it's strange to me seeing the sprite of chao falling. It's a little bit off, like stange to see at its legs and eyes.
I think that's only I want to say, don't know or remember what else. It's up to you to take my advice and start fix. Sorry if it's too much or I said in a wrong way. Anyways, you did a good job at this project.
