Calling the whole thing Prototype might be underselling where it's at somewhat, yeah. I'm still not sure how hard to push the Diagnostic View mode's filters and its gameplay at the moment (how difficult was it to walk the corrupted path down to the Core Memory portion of the tutorial scene?) but it is more than just a framework as-is I suppose.
I look forward to your impressions as the project develops. There's a lot of ground to cover (for instance, the entirety of the introduction isn't in right now) but I hope to finish it up with 1-3 hours of gameplay.
