Just a short update... I just added water into the game! It looks pretty good, you have to admit that.
The soldiers look a bit funny when they swim because they don't have a swimming animation yet, so it looks like they are just walking on water.
And there's one more cool thing in the picture above which you unfortunately can't see - there's a river stream defined in this level and the water flows. I did it so that it's quite subtle and you have to stop and look for a second to see it.
So finally I can make a level titled "Smoke on the water". Ha!
