Thank you for your comment! I'm really happy that you enjoyed our game so much! I sure can give you the solution to the case 😌
the weird lump goes on the beach (1), the tinfoil mess on the campsite (2), sunglasses on the restaurant spot (3), and the ripped cloth on the toilets area (4)
Since our puzzle/mystery is super clumsy (we ran out of time for a proper playtest), chances are that you will not find the resolution satisfying, but I hope you'll find it fun anyway!
(don't mind the multiples edits, that's me trying ro put the solution in spoiler, and miserably failing )
