Pre-Alpha Snapshot 22w41a

• All difficulty buttons function properly
• Animations for starting up the game, going back to the title, & player death added
• Added player health system
• 3D demo level accessible through newly implemented level select, or practice mode
• Added pause functionality
• Intense difficulty now warns you when selecting, like Doom's NIGHTMARE! difficulty
• Background in 2D demo changed to black
• added doomguy grunts that play when you're out of turns

Also sorry for not updating for 2 weeks, the pause menu got out of hand & school's been kicking my ass.
