Scratch

Anyone who would like to help me do the following;

1: view this project: http://scratch.mit.edu/projects/tree-hugger/3000045

2: Comment; what do you like and dislike and also how I should change/fix this project

3: download the project

4: come back here and post ways I should improve my script (especially my engine)

Information you should know:
The engine I have is meant to jump, with gravity, allow bitbot to glide for 1.5 seconds than fall.

Questions to answer:
Should bitbot be able to glide?
What would make this engine better?
What else could I improve on?
HOW should I improve on it?
What scripts would make my project better?

ALSO! View my code page any suggestions for fun codes? For example the code "RAINBOW" will make bitbot rainbow colors. Type "rainbow" into the demo and see what happens
