Wow...very hard! I'd prefer it if you could take out the guards but lost points - levels could be rated according to number of casualties. That way you could progress through levels and go back to ace them later, rather than just getting stuck.
Looks great, but a few of the solutions are somewhat far-fetched...buddha + steel rod = crowbar? Really? And often it's too dark to actually see objects so you have to click randomly to find hull breaches etc. But 5/5 for being top-notch anyway.
Lots of fun but a wee bit easy...still, 4.5/5.
I also had the 'green zombie can't kill enough to finish the day' bug - refreshing the page and reloading my save did the trick, though.
Meh...looks great, but not very satisfying and all a bit random - dice-rolling's fun but when it's all done by the computer you lose half the point. 3/5
