Invasion 5 is well underway now! :)
Just thought I'd show you all how it's going at the moment, and ask what changes and additions ought to be made before I get too far into it:

Don't be surprised if the units' stats are unbalanced, I haven't tweaked them at all yet.
Of paticular note are the 'speed changer' controls (note that you can't deploy troops while you're at 0x speed. Otherwise you'd be able to send out all your units at the same time, so that less of them get taken out by arrows).
So, what do you think so far, and how well does it run for you (the whole point of this sequel was the optimizations I was able to make to the game's engine)?
The game looks pretty much done (it's basically been remade to the point where Invasion 4 was) but I have a lot of new things planned for it that have never been in Invasion before. I won't specify precisely what things, though, in case I end up not adding some, and have you missing them. :)
