Okay, here's the good ending walkthrough:
Left-click until you reach a choice that has the following options:
- [Something to do with failing/giving up].
- [A different option].
Choose [A different option], and then continue to left-click. Eventually you will reach the good ending.

In all seriousness, I tried to make it pretty obvious which options will lead to good outcomes, so you shouldn't have any difficulty. :)
