I would say my day-to-day time improvements have been levelling off. In general, I'm putting in completed runs around 6m 30s +/- 10s, with my new record being 6m 18s. I did change my keybinds partway through the week from the arrow keys to WASD which messed with my muscle memory a bit, but I think I've mostly gotten through that now.
Point being, I feel like I've generally hit the plateau for my current strat and I can take a step back and move to optimizations for a while, settling on a more optimal strat, and then kind of repeating that process until approaching a point of very diminishing returns. Will reassess the project after that.
Along those lines, I've finished mapping all 8 levels so they can be reviewed during theory crafting:
Upon review, I've already come across a few "easy wins" in terms of optimization (to be verified), and have several other leads or areas wanting for experimentation. Enough on that for now.
A quick list:
I think that will keep me busy for a while.
