Good Core Concept - Could be expanded by having button locked until cactus pick up an item in the level, different hazards other than clouds which could then also interact with the blocks differently.

Keep up the good work!

Good, but needs more

Great work, but would love to see a sequel.

Thing i would like to see:
the option to fire the guns yourself
a choice of cars at the start, cheep ones to do up straight away and more expensive kitted out cars
levels, you have to get a certain distance then the map changes also new levels give new gear
a level randomization mode where each time its different
aesthetic upgrades to car like paint job and decals
