If I had money and this were a commercial project, I'd hire you as a play tester. Yes, you've found all the +MPH implemented so far and you're correct that certain events can't trigger on the first day. It's very difficult to trigger the healing skill on this first week. Companion health must drop below 35 for it to happen, and I didn't really want it to be a common occurrence on this first week. I may have overshot it though and made it too unlikely. I'll look into rebalancing it.
Thanks for your praise on the art style! It's the part I'm least confident in. Please stick with it and we'll see Eva to the finish.
