The Silent Platformer with No Platforms

NOTE: The last level of this game is cursed. There is a silly bug in the game which affects the last level. Please ignore that? Everything else seems fine. Thanks. Following goes the actual description.

This is a platformer with no platforms (and no sound because I ran out of time and also I had no title for the game, so my situation gave me this title).

You have to build your own platforms.

You have a gun. 

You shoot platforms!

You shoot some more stuff!

Time slows down while you aim after you have clicked the left mouse button. Releasing it brings the time back to normal.

Controls:

W: Jump / A: Left / D: Right

Move your Mouse to rotate the gun.

Left click to shoot.
