Some great feedback here. Most of your problems are just because we're so early on in development and not had a chance to do these things yet.
1. This might not explain things very well but have you looked at the ~1hr video at the top of the page? It goes through the entire game but doesn't explain button presses. There's also the Handy Quickstart Guide in the description. However, yes, we do plan on putting in a proper tutorial and we'll be rolling out more how-to videos as we go. There's a lot to do!
2. There could be a couple of reasons why this won't work. First cereal can only be planted in soil without weeds. Second they'll only plant into tiles that are the same as what you taught them. So for instance if you teach them to plant into Tilled Soil but there's only Soil left they will wait until you till the soil.
3. We're working on that :)
4. When you're in Edit Mode press the DEL key to go into Delete mode.
5. We're working on that. In fact the first big change for scripts will be happening in the next couple of weeks.
9. The next version will address some of this.
10. This is on our to-do list.
11. This is on our to-do list.
Thanks!
