Thanks for commenting, and it's valuable feedback. Ideally I'd like the red things to come from any direction, so an indicator of where they were coming from would be handy - but for this jam I just thought limiting it to one direction would save time and then I wouldn't need that. And yeah, you are supposed to have troopers (green blobs to the left of the outposts) who do the fighting and use up supplies (orange blobs to the right) fending them off, and you can build up defences (awkard L shapes on top of the outpost) to improve the trooper effectiveness. Then it would become a game of managing defences, troop transfers and supply lines. First time doing a jam and an RTS, and the detail needed in the calcs and balancing of only this small number of things in a short space of time took me by surprise.. definitely something I'd need to practice more before trying it in another jam.
