I got to level 9 but I could make it further! Cool game. First thinking about the transformation between overworld and dream, and then trying to apply the same transformation to the goal world. Original!
I couldn't get the rules of the game after trying a few times. After about like 10 attempts, I realized the concept. The "dreamland" is a bare field with tree seeds planted. Use parasols to cover areas to prevent tree growth, but the "dreamland's" field is at a different point of view. It's hard to explain the rules in words, so I would suggest a few tutorial levels so the player can get a better understanding by trying than words alone. It's a clever puzzler, but I feel the life system isn't ideal to have. I can easily come back to where I've left off as the solution to previous levels remain intact.
Thank goodness for an option to turn the background music off. It took me a few tries to figure it out. I think you could probably explain the instructions a bit better with a tutorial level or two. Overall it isn't bad, just a bit confusing at first!
The game was quite funny (especially what you wrote). The concept is interesting too. However the music sounded a bit too "synthetical". But good job ;) I loved your sense of humor
Either way, the take on the theme of dreamland being beaches and umbrellas, I thought that was a cool idea. Nice game, good work.
