The color-changing puzzle was wickedly hard, and super satisfying to beat.
It took a long time to figure out how to move the "log". I tried picking up several likely-looking things, and it turned out to be the first thing I tried, but I couldn't make it work at first. I have found that this game is generally very picky about being off by a few pixels. If I wasn't completely outside of a square, facing the next one, the action button wouldn't do anything. So that made the controls a bit tricky.
The spade/hoe timing was simply too difficult for me, but it was fun to try. I was able to solve the other three, and they were all really fun! I'm really impressed with the puzzle design.
The audio was excellent. Overall, I liked this game very much! Well done!
