Use the arrow keys to move. Try to kill Flowey. When the meter is DARK BLUE then press space to deal damage to Flowey, except you'll just 1 hit ko him easily.
Flowey had a nightmare on May 8th, 2016. This is the nightmare, except he was too dumb to actually notice his health go down to way beyond 0. Probably. (this is a poorly made project lol!) Credit: @THawk108 (Original Project)
