hey! great game idea!
i must be honest here, i think you prob overscoped with this game. pathfinder? multiple unit selection? fog of war? dude thats a full RTS game! youve implemented a lot of hard stuff in the jam timeframe and left some important and easier features (like sound and a basic text ingame tutorial) unimplemented. you must be a very skilled programmer, so be extra careful to not overscope projects ;)
