I've been doing some streams for friends this year over Discord. The most recent of these is a personal replay of Crash Bandicoot 4. It's a pretty niche title that I'm sure no one's ever heard of.
Anyway, the stream runs have only been covering the normal stages with none of the extras. Those extras, like the inverted versions of levels, are being done on my own time. Those levels generally have a visual filter added to them for better or worse. In this case, you'd think underwater slow-motion physics would make things more difficult, but no. This was actually pretty simple to nail after a 15+ death run last night in the normal version of this.
I'll just say one last thing. Don't mess around in the last part with Crash. The slow-mo physics might seem like a benefit, but those transport crates aren't infinite. You still have to go, go, go!
