Hi! I saw your mod when looking through the modlist looking for a specific idea and this was the closest thing to that I've seen on the site. I saw that you have a patreon and there's an option to employ you for a mod. I'd be very interested in paying ~$100 for a specific mod that's pretty similar to this one (mostly just transferring this to a regular freeplay map with some other small changes). If you're interested in this please let me know!
do you have an idea where enemies would spawn, what they would attack and whether you'd have to launch a rocket every x waves?
maybe the player could start with a rocket silo or some kind of flag,
you know you could have got abertPC to put his contact data so you won't get spam requests [not to be an asshole just saying cause I figured that you wouldn't want to deal with the spam]
