Well done.
Firstly i wanted to say that i was impressed that i was actualy entertained by watching the tutorial. And i wouldent mind if it were a bit longer. A few obvious game mechanics took me a while to pick up like clicking during animations to fast forward to the point (like when heading to a shop), or actualy moving the tank by turning the leaver.
The only thing that degraded my playing experience was a flash problem which left some things out of my screen (might be a problem on my side though).
still, 10/10. Inventive and fun game, nice sounds, good humor and ambientation and a well thought gameplay..
