2dPlatformer

! ! ! Notice:

When I tested in the browser, the D key didn't work, and I don't know why. So please download the client to view the homework, thank you very much for your download.

Here are my modifications:

1. Redesigned the first level

2. Multi-directional moving platforms are added to the second and third levels.

3.Added flying enemies in the third level

4. Modified the prompt sound when the player receives damage.
