Fixed some feedback

I fixed some bugs and changed some feedback by you:

• I changed the color schemes from the tutorial and last level; I'll do the houses later
• I made some controls and paths more clear
• I removed the pink blocks that turn you around. Now you turn around when you touch a wall  (EDIT: not in the houses lol)
• I made the input more responsive

If you have feedback, please tell :) (by the way, you can't describe it as precise as possible)
