Omega Flowey: Z to create a vine, X to use an Eye Beam, C to use the Mouth Beam, A to summon a Dentata (do not spam this one (or do, i don't care)), V to fire a finger gun from the side of the screen, E to summon nukes, D to use a soul attack (Do NOT spam this one either), F to spawn healz, and once 6 soul attacks have been used, press R to enter the final phase! Soul: Arrow keys to move, Space to attack at the final phase. Note: Omega Flowey can still attack while in the soul attack phase.
Thank all of you for supporting my Undertale projects, to Toby Fox for making this wonderful game, and to all the people who made the sprites. Update 1.00001: Balanced eye beams to reduce lag. Added final phase. Update 1.00002: Made it so that soul attacks stop at 6, like I meant for them to.
