This was a really fun and unique TD game! Others have already pointed out why, so I won't repeat it, but I'd like to mention that on my first playthrough I got softlocked because the little enemies got stuck in a blind spot where they didn't move and nothing could hit them
Hey, sorry for not replying sooner, I didn't notice your reply until now. I didn't take a screenshot of it at the time (although I totally should have, sorry!), so I had to edit together roughly what it looked like just to give you an idea, the enemies kept walking straight to the right, not following the path and there were no towers which could damage them, resulting in a soft lock
I couldn't paste my recreation into the comment itself, so here
is an external link to it. Hope this helps!
