For level 9: don't wait, until the acorn is in front of the spring and doesn't moves. You have to activate the spring, while the acorn is still in the air to get enough power! You'll probably have to try it a couple times, but it isn't that hard I think. Good luck :)
Hey, it's a game! Just play... but how? the "help" page doesn't really help, so there should be a tutorial, where is explained, how to solve these puzzles step by step... 3/5
I really love this concept. I played it on easy and completed it. I played on hardest difficulty and failed hard^^ Maybe its a little too hard, but challenging to improve the gameplay! 4/5
