For your remix, add your own character or customize the base. With every remix, add more moves to your character and take turns remixing. Do not add your own character into someone else's remix chain without permission. Use common sense: avoid using overpowered instant-kill attacks and invincibility. You can create a small ability that grants temporary immunity, but make it have a cooldown or a weakness. There are tweening blocks in the project for smooth movements. The SFX sprite contains a few sound effects from Ultrakill. Overall, have fun!
All the music sound effects are from Ultrakill, created by Hakita on Steam. Also btw if you ever remix, just comment on this project with a link to it. :P
