Thanks for the feedback, we know we still have a way to go with the mouse/keyboard controls and it is super useful to get any feedback on specific issues like this, they were quite a new addition this year so still need some time to iterate on. With the next update we'll be continuing to refine them and will take a look at the trackpad situation you mention!
Likely the next update we will lengthen the day cycle to see how it affects gameplay, it is something we need to find a good balance on and further in development it'll be interesting to see how it feels when you are living your life so to speak!
I'm not sure what you mean by the spirit sites? If you mean the two areas with 'particles' coming off them then yes they have a purpose! (in time we'll be making them more easy to understand as they are quite WIP in look and consequently how understandable they are...)
With the kickstarter tiers, the first one is referring to when we are aiming to have the early access version available in Dec 2017, the other tiers all have items that will likely coincide with the full release which we are currently targetting for Dec 2018. Hopefully that makes sense?
