AL-WAYS Hungry! v1.1 !

Made some minor fixes to the game :

• Added the total number of crystals you can collect in the endgame screen
• Added an ingame controls explaination, simply press SPACE to display it
• Added a pause menu, with the ability to go back to the main menu
• Made a slight modification to the level design, to make the position of one of the crystals more easy to find
• I recently noticed that the game wasn't working properly on some web navigators, so I made a downloadable version (only for windows at the moment)
