I don't have time to do mod right now. But I read all the comments, so I'll fix it as soon as I can.
Edit: I made it so that now the cubes will be added with the level. The change is minor, so I won't put it in the update log.
Okay I'll try to fix it as soon as I can.
Edit: I fixed it
Dude, if you do that, that would be really cool. Know that at least I would like to see it! I don't have time to do my own mods right now and update this one (it's just by the way)
It looks like there's been some kind of glitch. Now I have added a button.
