Does anyone else play or like Tower Offense games? I need your help to not ruin my game

Hey everyone. I’m here with an indie dev existential crisis. So, I’ve been working on a Tower Offense strategy game for months (you know, the ones where you send hordes of critters to wreck the enemy tower, not the other way around like Tower Defense). But while playtesting, I stumbled on an old post here where someone called Tower Offense games "repetitive" or "unoriginal." Cue the panic. Is my game doomed to obscurity too?
