Nice work. The sounds and music blended well and gave the game a very pleasant atmosphere, and the graphics, while not particularly flashy or eye-catching, were also pleasing and facilitated the game's feel. But this game is held back by some odd design choices.
Some important things aren't very clear; tree branches and trunks are solid, unless you're going the bottom, in which case you can pass through--but there's no indication of that, so I easily could have believed the entire tree to be a solid wall and given up at the second level. If you added a semi transparent section or something at the bottom, that would be helpful. More importantly, each level has only one exit the game will allow you to leave through on the left side, yet usually most of the left screen is empty and blocked by invisible walls, which makes the game's puzzles and trials to reach the "true" exit feel contrived and forced. Adding a visible wall over "false" exits would help tremendously.
Finally, I think the game was a little monotonous after a while... variations on common block/switch puzzles gets tiring after a while, and you didn't offer any new mechanics as my interest waned. This particular critique may be something personal, as I've always been partial to more fast-paced gameplay. I'm sure your game appeals just fine to others.
Overall this is still a good game, and a very solid entry into comp04.
