I'm enjoying this rather laid-back game that's more involved than most web games, but not so much so that I can't see the end in sight.
I have two interface suggestions to make it more enjoyable.
First, separate the sound options into music and sound effects; volume for each would be good, but definitely make it so I can mute the music but keep the sound effects. (I like using my own soundtrack.)
Second, when in training, the combo counter resets too quickly. For example, when I have my block combo up to 100 there are about a dozen apples coming at me all at once. If I miss one, I usually block another one before I even realized I didn't block the previous, so the max combo is gone before I even look at the top of the screen. Solution: don't just provide the currently running combo. Also show the previous combo (only if more than, say, 3), the best combo, and the combo needed for next medal.
Browser (Chrome Version 37.0.2062.124 m) locked up until I closed the active tab. Reloaded the game, and I'm starting baby fresh at 0 (was 53) as "Guest"... didn't load the saved game?
