It did feel out of control, but a little too much on the iddle game-side of things? I wish I had more way to interact.
Another problem is that when you have so much coin everywhere, it does not feel very appealing to try to collect more. I think if you had very few of them, I'd have gone way more distance to try to collect them, because I'd have felt emotionally attached to them?
Unless you really wanted the arcade appeal, which I can understand I'm just not the right target for.
Very nice art and music
