I've only reached up to 200 in the counter but overall, while the art is cute and gameplay is nice and easy enough, there's not a lot going on to keep you engaged here. I was hoping for my high score to save or for something to unlock (an achievement, perhaps) but nothing. :(
This actually has a lot of potential—especially since it's a fan game of Porco Rosso, which has numerous flight scenes. Perhaps not just evading the planes but even their aimed fire, as well, for later levels to give more of a challenge.
