I don't mind at all, you can link my video! :)
The Level 2 Square Barrage Spiral is doable for me by all means, but there's some scenarios where I feel like completely holding the same button down would keep me alive since I once cleared 2-3 Barrage Spirals, a couple Inverses and I believe 1 Box w/ Cap pattern all in a single turn before, with back to back Barrage Spirals I might add.
I knew something wasn't right with Level 2 Hardest with how unbalanced and broken it was, not to mention the Alt Barrage on Hexagon spawned impossible variations that not even I could clear with perfect movement, it just seemed very luck heavy and I had an attempt that could've saved me a whole 30 minutes from recording if I didn't die last moment, it really got on my nerves.
I figured Level 6 Harder & Hardest were disabled since 20 completions from 7 levels overall is basically impossible since it'd be 19/21, so that I knew was on purpose for the demo, otherwise I don't know what I would've thought about doing that.
