Wasn't able to beat it, so I'll have to replay it later to try again, but overall I really like the concept. I think it's really cool having to strategize ahead of time what you might need to deal with certain issues. I also like how you can take risks for cans. And I also like the idea of the amount of cards you have being your health (Though those flying chip enemies are hard to attack and always get me a couple of times). The farthest I got was the city level.
Very creative, charming little guy, and I'm also a fan of the art.
