having popups for using items would be nice too(ie. how much AP a grenade costs to use. also how far the grenade goes could use more AP as opposed to throwing it only a few squares away costing less)
i enjoyed this game a lot, but found the loosing conditions way too easy causing frustrations,
adding a end turn on spacebar function would be very convenient.
try to bottleneck the creepers focus on building only a few things at a time.
Dont try to expand too quickly. unless your trying to get to a more defendable area. if a unit is no longer useful in an area you can move them.
drones are your friends when trying to expand into enemy territory
If you wait a day someone will turn up and inherit the farm
