Help with Speeding Up Code

I have developed some basic code for simple movement (i.e., left, right, jumping, falling) that relies on only background color and code inside just one sprite. It seems to work fairly well, when run in turbo mode. However, it is WAY slow in normal mode. I would appreciate any suggestions to speed it up without loss of functionality. As an additional note, I am noticing a small bug that could lead one to “teleport” across the blocks, but I can't seem to replicate the problem consistently. I would appreciate help in fixing this issue as well. Thank you very much!

Hi kiddynamo,
I looked at your project, and it looks really good! I like your use of binary numbers in the variables, and the coding is really good for a new scratcher (you must have experience coding!)
My only suggestion is that you make it move more for each button press. I'm not being very clear, so look below:

Instead of something like
when green flag clicked
forever
if <key [left arrow v] pressed?> then
point in direction (90 v)
change x by (-1)
end

Maybe you should do
change x by (-3)

And also apply that to the right arrow key. Good luck!

Sorry, I didn't put the scratch blocks in properly. I'll fix that

Another way to speed up the code is to try and reduce the number of repeat forever loop.

Instead of
forever


if <key [ v] pressed?> then

end

end

try:
when [ v] key pressed
