Click or Press space. Try to stack the blocks as high as possible. Check Cloud data for highscore. All art and code by me (@kriblo). This is a remix of my project Stack (link above), but using clones. In the Block sprite, there are 200 costumes with widths from 1 pixel to 200. Also, there are 8 backdrops, to animate the scrolling. These were all created using Notepad and a Windows CMD batch script.
