I just uploaded a quick HeroMachine 3 update, word balloons in the Background slot!
You may wonder why they're centered -- it's because that's the center point for the Background slot in general, most of which are full-screen and so make sense to be placed there. If I put the word balloons where you'd expect them by default -- upper left, by the head -- then when you rotate them, they rotate around the center point and that's irritating. Plus, you then can't manually drag them over to the left, which is also irritating. So instead I chose this slightly less irritating method whereby you can drag it wherever you want once it's placed.
If you have other word balloon shapes you want, let me know in comments.
Yes, I am still working on Musical instruments but they're slow going.
