Death Unphased is part of the Dreamhack Beyond Summer Indie Showcase running from August 18-27: https://store.steampowered.com/news/group/40157993/view/6533084468191083425.
To celebrate, there will be a pre-recorded demo playthrough (no commentary) demonstrating how to earn all the S ranks!
With the freedom to phase through walls and spikes with your dash, you can invent your own path in Death Unphased. But be careful - hovering ghosts, unphaseable acid spikes, and more will complicate the route to the exit. It's up to you to search for the fastest way to speedrun each level.
Development remains focused on levels and mechanics for release. But for now, you can enjoy the demo and wishlist the game!
