Controller support!

(Kinda...)

• The game now has limited controller support! You’ll still need to choose the level in the main menu using the mouse, but once you're in the game, you can cycle through levels - whether you get spotted or complete a level - without needing the mouse. Just press any face button or Select/Start on your controller.
  Note: the REDO function isn’t available yet (because of how the app is built - class dependencies and all that), but full controller support is planned for the future!
• Added extra control layout for keyboard as well - you can use arrow buttons instead of WASD if you prefer! As with controller you can press Space or Enter to enter the next available level without need of using the mouse!
• Normalized movement, so diagonal movements are not 2x faster as before .
• Fixed some enemy detection bugs.
