Gentle push: just figure it out
get all fruit
get to right wall and shoot sick at floor for like 1/2 a second then jump, and keep holding in sick and you SHOULD go flying into the air and get to the exit
1800 trick points: get full wheels and rockets and then buy superman, get the two poles right (up arrow bits) and face ur rocket upwars, then keep tapping up up down, so u jump in and out, as you land with about 1000 points you will bounce, giving you time to get 800 by tapping handstand
For hard.. just get big rocket, and racing wheels, get your angle right, and keep jumping in and out of handstands, till u get near floor (you should have bout 1000) then you do a few handstands when bouncing (they 200 points each)
