press space, and my newly added flowey will change costumes! it takes one second to recharge so there won't be my flowey changing costumes like crazy. oh wait, he already does. go to notes and credits to see credit to..'s. i also changed things a bit so mine was at the front. enjoy all my hard work. nothing else.
credit to @SomeHoboAgain and everyone else who remixed, also undertale for making this possible.
