Hey thank you so much for the feedback! Please do post a video here.
I know exactly what you mean with the grabbing - there is actually a delay which is probably a bit too long before it registers that you want to grab an object. This was to simplify the controls so you can use left click for inspect and also grab. We wait a certain amount of time before grabbing to see if you release (for inspect). Anyways - I will shorten that a bit and see if that improves it for people.
I wanted to keep the settings simple, but I think I will add a move speed/mouse sensitivity option in the menu for people.
Regarding day length, I didn't really know what would be ideal for people, but I will try adding another 45 seconds to it and see how well it goes.
Keep an eye on my dev log as there should be an update with these changes later today or tomorrow.
