The Omega Flowey Fight Simulator -2021- is a browser-based fan game that recreates the final boss encounter from Toby Fox’s Undertale (2015). This paper analyzes the simulator’s mechanics, audiovisual design, and cultural context, focusing on how the 2021 iteration differs from the original and other fangames. We argue that the simulator serves not only as a nostalgic tool but also as a case study in decontextualized boss-rush design, mechanical difficulty scaling, and the preservation of memorable game moments through interactive simulation.
After "dying," the six souls in the tanks refuse to help Flowey. Instead of a single "SAVE" bar, the 2021 simulator requires you to click on each soul individually while dodging Flowey’s final, pathetic pellet. Miss a soul? The fight continues. Land all six? Flowey screams, "NO! NO! NOOOO!" and transforms back into a helpless flower.
