this gimmick did remind me of bloons td 6 which i thought i should add
the enemy movement system is kind of bugged, esp if you leave no path for the enemy
i think this concept is unique but being able to rotate every tile might be a nightmare for balancing, and there's not that much incentive to change the tiles once we do get a solid defense down
so i think if you could guarantee an enemy path for every combination but add an incentive to switch up tiles then the concept could benefit a lot from that
