It Is Awesome game, good job.
Reviews for "Dr. Null"
I liked it, it was a good time waster and lots of fun. Though I got really tired of clicking and I need hotkeys to buy...
That was fun! :D Appreciate how you can start over from the last wave as well, or that secret teleport would've been pretty cataclysmic! The upgrades, the action, the variations of weapons and enemies... it really does build up a game with plenty of re playability and good old arcade fun. Just keep the carnage going! Nice work.

fun and challenging
The strategy guide helped out a lot.
