there's a bug; when you ask him "what would I do with 1 million dollars" then click "refuse" with his answer, the next page that comes up is some answer in regards to vomiting up his taco if he asks out a girl called Angela.
On all training levels when you have reached level 150 (except climbing) it does not indicate that you have reached the maximum level after you die(or indicate to return to the shop etc). When you die, the bar indicating the percentage of your training is always at 75%. In the cheats section, the black crown does not show up on the chicken when you return to the main menu nor do the other cheat accessories appear in races.
when you have reached a max level and it tells you to go to the shop, if you hit the spacebar twice you can continue on with the level and continue upgrading without having to buy it.
nice game, rated it a 3/5. Mouse response time is a little slow, it would also be good to have an option to save the power ups as sometimes they were completely useless and came just at the start of a new wave.
