congratz for finding out one of SM's easter eggs, it's not a bug btw

I've faced him 4 or 5 times now and I'm level 12 I don't have any knock back effects on my guns and can only teleport once so he always beats me I've come close to beating him though

If your cornered, you can use the jump ability, but if you have wheelies, too bad, but with wheelies, you need a weapons that does knockback 2 or more, but some knockback weapons are limited
