Cute project! Couldn't see any telescope though. But there may have been a bug when I picked up the object on the boat, it kinda looked like a telescope but when I got it it was a trumpet ?
Unfortunately, no. Maybe I saw badly and somehow let go of the object ? Is that possible? Couldn't find it anywhere, it was the last thing to do the telescope.
I think you tried to pick-up two items at once, which shouldn't be possible but is due to a bug. That'll break your game. Due to the game jam having voting I can't update the game for another 7 days.
