I agree with a lot of previous reviews. Upgrades are really hard to get, especially when needed on the challenging levels. I just played a level that I couldnt do without using the speedy boost. On my Facebook linked game, I am in the space ship restaurant and I the rockets are two hard to keep with when there is two at a time and I can never get enough Dinero to get the robot that helps with that. Upgrades are way too overpriced. Id have to wait like a month to watch enough adds to get the upgrade needed to continue playing and it really isnt worth it. If the boosts could drop to at least 5 and the upgrades to at least 15-25 it would be a lot more convenient.
