Here's my no-commentary playthrough:

I did a second run and spent about a half hour leveling up at the gym so I'd be strong enough to enter the lighthouse, but apparently it's a sick joke. Tried going in with a STR level of 3 and it still didn't work. So that was kind of shit. Other than that, this was quite a fun and unique experience. Great work!

Dear Presenter…

Thank you for your usage of the software. Our software is certainly NOT a sick joke! We will put our interns into overtime to figure out why the Lighthouse feature was inaccessible when the conditions for it were met.

We are puzzled and saddened by that discovery.

I hope you continue to use our software in these trying times.

Best, Presenter Slides Team
