About the screenshot, sure, no problem!
Yeah, I'm never trying an RTS for a game jam again. Maybe something like yours, isometric, place buildings, but that's it. Maybe a tower defense at best, but pathfinding, selecting multiple units, units spreading to take on different targets instead of piling up on the closest enemy, formations... it's A LOT for a few days jam. Still, at leasy yours is playable, in mine the balance is waaaay off and you either get destroyed on wave 2 or survive forever by spamming knights. :-D
