hmm...on second thought my flash player just crashed when I tried to switch ammo. The ammo type would not switch if I clicked it or used the hotkey; however, I kept clicking it, and suddenly it crashed. So, despite my nice first impression, I am beginning to understand why there are stability issues.
The game is seems pretty cool, at least with my first impression. A little improvement that I would like to see is a display showing the amount of uranium one has when the garage window is open.
