You use the arrow keys when you are playing as Toby's soul, and when you have the cursor, select a button with Z. As Lucas's soul, you can't move (on purpose) But you can jump/dodge attacks. Despite that amazing jump, It's harder for him to get the attack pellets. (NEW CHARACTER IS GOING TO BE ADDED INTO THIS SOON.)
You can change whatever you want, or even finish the battle. Inspiration to Undertale,@Br0nd0n, and things like that. I worked hard on this with my friend Dustin.
