V1.1 - Pause Menu, Slow Time buffs, and enemy nerfs

Hello everyone. I would like to thank the good people of Gamedev.tv for sharing their opinions about my game. I'll list what new features I have been added, changed and fixed.

• Added a proper Pause Menu

You no longer have to press ALT+F4 in order to quit the game, thanks flowtheci for your suggestion! (Your game is great, by the way.)

• Fixed "gluey" player issue

You may have noticed that touching a wall would slow down your speed, now that's no longer the case.

• Support for Mac & Linux.
• Slightly buffed Slow Time's consumption and regeneration
• Fixed the problem where the win screen wouldn't restart or take you out of the game.
• Added restart button.
• Added AI reaction time. These hiding behind walls should have a longer reaction.
• The enemies and the boss had their firerate increased.
• Nerfed enemies' bullet speed and buffed Boss'.
• Minor changes on the maps to make the game more fair.

I plan to add settings very soon, after that I will rewrite enemy's AI and hopefully create some new better levels!

Please let me know if you find any bugs.

Thanks!
