I could help you improve the graphics quite a bit. This is not shown in my current Kong games because they were very rushed and my new games which will be out in a few weeks will show my actual standard. Leave me a shout if you need any help neatening up the game!
Last level. Dont bother with the ball. Just take some mass from the first triangle and give it to the last triangle. It will knock the shape into the finish without having to do the other 20 triangles.
