Finally I finished level 10 and then went for the skull - WTF?? AWESOME!!! Top game I've played in months!!! (Minor gripe is selling towers accidently just after upgrading them)
Needs both a reset button so we can play again from the beginning and a continuation with more than 3 rooms. Also a second game with contemporary songs would be awesome.
Nice glitch - accelerating training races cost gold but you can accelerate even if you don't have any gold and it doesn't take off anything else either.
The Gamer is the hardest of all the levels including the bonus Castle level. Best strategy is to up-head right to stop that flow, put one low to prevent overflow there, and then build around the rim of the screen alternating collectors and blasters.
