Thanks for giving the game a try!
You're right. Level design, and some of the core features really aren't coming together, although a lot has changed since my last DD. But I'll be iterating on this in the coming weeks for sure. Hope there'll be more substance there. Things are always in flux, so as the AI and other content pieces come together, so too will the level design. Thanks for raising this. It's really valuable to me.
By the way, to do a basic power slide, just run and hit the Alt key. It's a dedicated button. I sadly forgot to include it in my rush job tutorial.
But thanks again! Hope you'll see more next time.
