Thanks a lot my friend. I'll keep in mind and try to make lower resolution versions of each map in the future. When I find time I can update also newest map packs with lower res so you can download them for free. I'll update you from this comment section so keep an eye.
About the pricing, I'm happy as long as my maps are used in games and people enjoys. I'm not trying to get rich but I want to keep this wheel turning so I can make more for people. Thanks for your awesome feedback!
