Pretty good. Graphics are great as usual. My only major complaint playing this is that a lot of the hazards aren't clearly signposted. For example I was surprised when the frogs, hedgehogs, and jackhammers did damage to my character because they look fairly harmless at a glance. The frogs especially since they are small and blend in with the background quite a bit. The closest thing to a visual indicator is the white outline, but the birds also have that and those are harmless. I found myself instinctively dodging the birds since I had associated animal = dangerous. Perhaps give hazards a yellow / red outline instead? If you're worried about it looking ugly you could have the outlines change only when they dangerous (i.e. when the frog prepares a jump or when the jackhammer starts chasing you).
