Adding to the comments above, I agree that you should be rewarded for looking after your resources (so keep the units you haven't lost and the resources you didn't use. Also all weapons should be available, but more expensive (hence the need to preserve resources to buy them). The units should be colour coded to see what's what. I like the buddy system of flares and fuel launchers - that works well. Definitely more scope for different scenarios (such as defending a town, rescue ship, settlers outpost, mining truck etc.
Excellent game. Lining your guys up to provide overlapping fields of fire is a great idea. Would like to see bunkers, turrets etc. (sentries like in Alien?) but can't really complain. It's just too short! Would like to see 10-15 levels at least. 10/10 for me.
