DEMO PATCH# 29 - Improved tutorial

[h2]New tutorial and more art[/h2]
Hey, everyone!

This is a quick update as I won't be able to post one on Friday, it's mainly art and a new tutorial so nothing too big yet.

[h3]NEW[/h3]
🔹NEW: Dynamic Updated tutorial.
🔹NEW: Some more art for big rocks, Grass, flint, etc.

[h3]TWEAKS[/h3]
🔹TWEAK: Removed right-click to cancel a placed building (accidental removal was too common)

Thanks a lot for playing!
