The Goat Cheese Solution for all :-)

Oh, thanks to the cheese below you can also easliy cheese Grandfather Paradox.
So, 1 cheese => 2 stars => 3 puzzles :-)

You can very easily steal both jammies and a hexie from Ring the Bell.
This cheese also allows you to grab both stars effortlessly and cheese the parmesan out of All Roads Lead to Rome without touching the buzzie.

All of above without solving any puzzle - I havne't yet solved any as that cheese was too tempting :-))

PS. The death invisiwalls are a trait of a sadist...

I have no way to get the second star, how can I obtain it

@shlam
Are you jamming the buzzer in All Roads Lead to Rome? If you don't, it will always navigate back to the fan and you won't be able to carry it.

Grandfather Paradox has fences above important drop off points which you can walk under to push the buzzer off, should be very consistent. Similar fences are not in ARLtR as buzzer placement isn't too precise and dropping while standing still doesn't push the buzzer far enough away to cause issues

As I understand, breaking out the second jammer with that jump requires the puzzle to be solved. The intended solutions for stars don't require any puzzles to be solved, so breaking out extra items with a solved puzzle is mostly a non-issue. But I made the wall slippery as parkour without guided jumps are not intended

Intended jammers for the star are 1 from Ring the Bell, 1 from All Roads Lead to Rome

Thanks, I was debugging line of sight and accidentally added a jammer

The update added more jammer. Which jammers are intended for the stars? It can be taken from the outside on the diagonal fan of “Ring the Bell.”

@Hardy P I overlooked that jump when I swapped to a lowering fence. Should be fixed now, thanks

@Nazario92
Thanks. While it doesn't matter too much how you get the jammer out, I overlooked standing on the pillars as an easy way to get the hexahedron out, so I moved the stairs and added a slippery wall. You can still break out the jammer there using a hexahedron on a buzzer, but it should be harder to get the hexahedron out

@Elyon Yes, All Roads Lead to Rome is slightly timing based, but it should be easy to do with the slow player speed without sprinting. I decreased the charge time on the receivers in Grandfather Paradox which should fix the cheese, thanks

Lovely set dressing, and I particularly enjoyed All roads lead to Rome and "Ring the Bell"
In "Ring the Bell" by the final fan, if you jam it, and place a box on it, you can jump over the fence and cheese it, just FYI

nice puzzles!
not a big deal, just reporting: for the "Ring the Bell" star you can bring the jammer jumping from here(instead of doing that from the roof)

The ending of my solution in All roads lead to Rome is a little time-based. I believe it's intended, but just to be sure I am asking for confirmation .
As for The Grandfather Paradox, you can cheese it by bodyblocking the upper laser yourself and then running beyond the plasma door .

All done. Good job. The use of the buzzer is unique. Will have a little trouble picking up the stars.
