As the title states I need feedback on a map I recently created, because I haven’t gotten much opinion on it besides it looks cool from friends I game with… Would like opinions from fellow members of the community who aren’t afraid to hurt my feelings. Below is the details I posted when I submitted it. Thanks in advance.
