Okay, maybe I jumped to a few conclusions. A lot of my thoughts had to do with your first video. It’s hard not to judge by first impressions.
In the first video of your walkthrough, you state almost immediately after the opening that you are unfamiliar with what uses for shards there are through the level. That means you weren’t experienced with the prologue while recording your walkthrough for it. You were also unfamiliar with the Jennerit chest appearances, with score and helix pickups, and you didn’t know what a thrall teleport anchor (I don’t remember the exact name) was. That’s why I thought your playthrough in general was semi-blind. Blind in this case meaning not knowing major mechanics or story elements about the game ahead of time.
In the second video, you don’t yet understand what credits do for you and voice an erroneous assumption that you can buy credits via a microtransaction. That adds to the “semi-blind” impression.
You (or at least your early videos) could also benefit from giving a lot more tips as well, such as advising saving those red shard canisters for combat for easy kills/damage, saving chests for mid-fight power ups, explaining your overall strategy behind your helix choices, explaining boss mechanics (henchman, I’m looking at you), explain what segments change across multiple playthroughs so players aren’t confused when they encounter something different from what you show, and so on. Pointing out those things, even when they seem obvious, isn’t patronizing when people are coming to you for a guide. Eventually someone is going to rely on your guide and won’t understand these things purely through seeing you do them.
Also, I don’t think it was unreasonable of me to assume this was a completed series since your playlist included all 9 stages, no other videos yet, and you waiting specifically until you had a video of each story stage before advertising your playlist.
