1.2

changes:
- fixed sometimes not being able to kill an enemy of matching color
- adjusted AI see distance & angle
- added little "detected" indicators for the enemies
- enemies can now alert (really) nearby enemies of your presence
- added a "search" state for the enemy AI
- added a difficulty option between moderate and hard
- ajusted "tutorial" level a little, still not enough
- enemies don't see trough each other anymore as easily
- fixed the dash amount carrying over to a new game
- adjusted the arena enemy count
- fixed enemies randomly getting completely stuck

bugs:
- alerted enemies sometimes walk backwards
- starting over with the hardest difficulty is now impossible due to the Dash amount needed at a point in the "tutorial"
