Choosing a botanist at the start, throwing a rock for 1 damage at the mandatory boss who has hundreds of HP.

Getting to the first town, no idea where to go, what to do, or even a functioning map.

Not being able to jump.

Unfortunately I wasn't able to enjoy 1.0 as I had it installed on launch day, and spent the next two days with my best friend as we tried to force ourselves to like it, to no avail.
