New Space Pew Pew

Hello,

This is my firs devlog i guess so basically here goes:

Changes made:

• Instead of game being wave based, opted out to create enemy spawns that as the games goes along will speed up spawn times exponentially
• Added sounds to player shooting
• Added new "Main screen" page
• Added Game Over page with Score and High Score so you, as a player, will be able to track your successes :)
• Added Main Menu music and in-game music so the game isn't a boring slog fest

That is about it, thank you very much :)
