Hi
Im busy making a project where you have to fly the bird.
The bird goes up and down with the correct keys, but a bit into the project, it starts to suddenly go wild and fly higher and lower than I ask it, going off the side of the screen many times... whats happening?

If you are using the "When () Key Pressed" block to drive the action, you might be having trouble with your computers keyboard buffer.  It might be storing up your keystrokes.  A better approach to using keys to control is shown in this project

It's hard to say for sure what your problem is without looking at the project.  Maybe you could Share it to the website?
