im tellin ya man you could make some money if you released this for mobile. I think I have the gamemaker extension for that on my computer if you need it.
Thanks, geekdude! It has been so long since I've used GameMaker, I don't even remember GML very well - I think if I were to revisit Hover Havoc I would have to completely rebuild it in Unity. Yikes! I am also not sure I have all of my pixel art saved anywhere - so I might also need to remake all of them. Double yikes.
