First off, thanks for the critical thoughts. You wouldn't believe how hard it is to get some juicy feedback like this sometimes.
A lot of what you've pointed out I'm aware of but actively am saving for the bit editing run at the end when the script if closer to completion. Mostly because of cost and to avoid multiple passes, but as the script is still being fine-tuned based on feedback, it'd be a waste of funds to hire an editor now only to have the section that I got looked over rewritten to better capture something the player-base has missed. As such though, it's a failing of mine for not being as consistent as I should be as far as commas and alike. Trust that eventually it'll be remedied.
As far as American English, I got tired of people claiming things like "colour" as a typo, and given (if going by the Discord server is an indication) there's less than 1% of players using/expecting UK English, I swapped over. The game itself isn't set in America though, just "non-descript northern hemisphere" to avoid picking actual locations for the freedom of geographical features as required by the story.
I'd be interested more in hearing your gripes with things that specifically didn't gel with you though. Partially the drama and issues with Path D. I'm not going to defend my creative decisions here, but additional data on why you feel the way you do could help me tighten the interactions for the better.
