Wow! Amazing job! It was super fun to hit the blocks into the blob things to make them explode! The graphics were superb! The audio fit well. :) Absorbing the crystals definitely fits the theme. The gameplay was a little difficult to get used to at first but was quite nice once I got the hang of it. Great job taking such a simple theoretical game idea (Collecting Stuff & Avoiding Obstacle) and making it so fun. I have absolutely no clue what the intro scene with Navley was about, but it gave me a smile looking back -- Thank you. Overall, Fantastic Job & Keep It Up!
I was only patient enough to get the first crystal of level three (It was kind of frustrating every time I barely hit the black blob things on accident -- Not your fault, just my error):

Postscript, why is the game called "Peach Trees 3D"? :)
