Some difficulty progression and remembering your high score would be welcome here.
Also, some more complex behavior for the enemies (and different enemy types) would be welcome too (perhaps having them move in different directions and bounce of the left and right side of the screen could give a nice challenge).
My high score after 3 tries was 5555.
Wow - this game is hard. This kind of gameplay should perhaps only be present somewhere at the very end of the game. In case you'd want to spend any time on improving this, I would recommend building up the difficulty step by step, and adding a checkpoint system (It may be already present, but I didn't see it as I haven't been able to get past the first set of green boxes).
Nice graphical style, relaxing music. A bug brought me back to the title screen. Since there's no replay value I won't play it again even if it would be fixed.
I really enjoyed the game and its depiction of nature. Very relaxing.
The 'boss fight' broke too much with this atmosphere, so I quit the game there. This kinda blew it for me. Could have been a lot more. Still 4/5.
Enjoyable game playable in less than half an hour. Great atmosphere, music and graphics. Easy chill gameplay, more a small interactive story than a game. No replayability value though. Some alternate endings would have been nice to replay this game and enjoy it once again. 4/5.
Couldn't finish the last level. It just seems to be about timing, so both balls hit eachother and one goes left and the other goes right... But I'm not patient enough to try again and again and again and again...
I reached a score of 20,000
