Made a Merge Pet game for iPhone, would love some honest feedback

Hi all, I’ve been working on a small iPhone game called Petopia: Merge & Collect and wanted to share it here.

It’s a casual merge game about combining and collecting cute pets. I’m still improving it, so I’d really appreciate any honest feedback on the gameplay, UI, progression, or anything that feels off.

Thanks to anyone who checks it out.
