Sol i know what you mean, i used to be a big fan of pocket tanks with meh brother. I have an idea how to make this, ill try to whip it up quickly.
If you manage to make it, you will officailly be a living legend. Between myself, Mipey, Zack, Dave, Shviller, and Deadeye... we have been unable to make something that works reliably on a pixel sized basis.
If you get something working, upload it and link it here... I gotta go to bed for now though I'd love to hang around lol.
