How do you make levels where when u walk more is made and swords i saw some like that and wanted to know

level size can be set in the tab on the right side. Swords cannot be done yet, but its planned. After a period of debugging, next comes monster editor as far as I know

edit: btw, no need to make multiple threads, if you devoted the time to search the answer, you would probably found something. In voxatron game folder you have a text file full of usefull info.
