Wall grind lets you slide down walls slowly and lets you jump off of walls. As for a code, this update thing is not complete yet, but you can find my old version a post or two down my play journal :)
This looks SOOO COOL! I can't wait until this is released. One suggestion though, I believe you you add more bosses that do different things. But even if you don't do that, I think this game still looks EPIC! P.S. I count as 500,000,000,000+ people, so I think you've built enough hype now...
An archer boss who shoots quick weak arrows, a mage who shoots slow powerful fireballs, a juggernaut who moves very slowly and has a LOT of HP, a healer who heals themself while fighting,(continued in next post...)
Shadow-You (made up myself) mirrors your actions but has a slight lag behind you and your items. Only way to beat him is by dodging out of attacks at the last second since he is slightly slower than you.
