Using X to clear is annoying when making quick actions. Can't SPACE or X be used for building/demolishing? Seems unnecessary to have the extra button. Or, could the button be on that isn't next to the toggles?
You are quite right, I did think about having objects be easier to delete. But through play testing I found it to be quite fun to scroll through the objects and remember where each one is. X I don't know why I added, figure it must have been easier to just separate the key presses.
Thanks for playing though.
