Change log:

• Tweaked lvl 1 and lvl 2 starting speeds / goal speeds, the game pacing should be improved for new players
  -Reintensified background particles. They move now slower than previously, so afforded to intensify them without causing hopefully too much visual distraction effect to players.
• Pause feature. The game will pause after 2 seconds when player enter the menu, this is so that player wouldn't cheat the system with the instant ability to pause.
• There's more goal scores on each level, so the urge to keep playing should be increased
• Lvl 4 had quite low background particle visibility, increased it
• Spawning triangles used to cause visual glitching at the corners of the screen
• Increased the speed that the obstacles appear at the start of the level
