Very interesting game
What I thought was really cool about this game is that it had such a strange scenario put onto it. Some of the machines looked like they were horse drawn and the others were more modern. I guess I'm not that good at it, as I did not even realize that there were more enemies on the other side of the screen! The best effect is probably how you can focus on shooting one enemy. You do have to be quick as these guys eventually come after you. It takes much strategy to get past even the first level.
I really liked the graphics and thought it was as good as most of the really good stuff you have made. It is interesting when a game requires a lot of strategy even though it has a simple outlook. Even then, it manages to look nice all around. I guess it would be too whiney to suggest the gameplay be a bit easier. At least some people are acknowledging the importance of World War I.
