I got 28. Eventually there's just too many enemies on the screen for me to dodge them all! Good times; solidly playable. I wish it was a bit more clear what the various seasons do. There's the big skeleton with lots of apples and the summer where the apples despawn quickly, but the other two?
Yeah, eventually the enemies hit a point where it's really difficult to keep track of them all. The autumn and winter seasons aren't differentiated enough, the only real difference is that autumn spawns more enemies, and in winter the apples last for longer before disappearing.
