Thanks! ^^ I thought players could figured it out, but in the post-jam version there are a short tutorial that mentioned it. It would be cool if that would be a heart instead of a skull?
Yeah, I mean it only took me one hit to realize that so it's not that bad. Maybe changing it for a heart or doing some really small level/tutorial that clearly shows that the enemies are going to the center could work (because that's what I didn't see, just a bunch of enemies appearing).
