Features

In this PR, I added a screen boundary so that Mario can no longer go offscreen.
Items also no longer get stuck and glitch on monsters.
Jump height was modified so that Mario can make a four block high jump without momentum like in the original game.
Monsters can now be killed by jump-punching the block beneath them.
