Just press the space bar to continue. And it looks better if you wait for the sprites to all glide of-stage before pressing the space bar. Please tell me in the comments if you want another project about Giga, Nano, Pico, and (yes) Tera.
I feel bad because, with the limit of 3, I also left Tera out in the tags :( (Btw, you won't really get this if you don't watch)
