This is my submission, at the time of starting this, I thought i had a chance of winning, but now im not so sure the other submissions are really good. This one didn't really turn out exactly how i wanted it to but its pretty cool i think Also if you add this you can tweak the particles and stuff if you dont like them. Also its 2 sprites (the character has code and then there's the actual aura)
Song is Remedy from Undertale Yellow. Credit to @ColdBloodedCoder for the character sprite and for the contest.
