The normal flame thrower doesn't stick to walls while power up one does. So how about making the normal flame thrower sticking to wall? Oh, add some effects on players while in sugar rush mode (like colour glowing around the player during sugar rush).

And when the player runs- a white glowing trail appears behind him/her. What about replacing it with fur colours of the player (Like if I use green fur- it should have green trail instead of white).
