First of all thank you so much for all the feedback this is incredibly helpful especially from an experienced developer.
About the jumping; it was something I considered at the start and I came to the conclusion that its more scary if you cant jump as you have less places to go (i don't know how to explain that). The terrain was a real problem especially considering godot is the best at 3d physics.
When i was playtesting the game with my friends some of them also couldnt find the shed but some of them found it instantly, so my solution was to remove some of the trees so you can see further. Markers is a great idea i just didn't think of that at the time sadly also considering the objective text was added last minute ; overall player game direction if definitely something i need to work on.
I was going to add subtitles and i had the text written out to do so but as with most game jams i just ran out of time and there was more important stuff to be dealt with. With the pitch black issue i had thought the torch fixed that and i never got any complaints about that so i didnt fix it, the reason you couldnt see the light house stairs might have been because i didnt plan for the player to walk downstairs before the time skip. About the lighthouse i intended to make it so you could only see it once you turned it back on which worked and the light house has a breaking down animation where the light turns of which means you can see it until you fix it.
The lighthouses invisible collider was added very last minute so i didnt have a lot of time to add a mesh and i js assumed you would be "hitting your head there" or something.
Godots 3D collisions are good but they most definitely need improving (I think its planned in the next version)
The file size was way to big for the content im aware but what it came down to in the end was textures and models which i could have fixed but i just didnt have time again, and i felt better after seeing one of the most popular games with a 2 gb download.
Thank you so much for this , this has made my day literally. I do think you would have changed a few points if you finished the game but thats my fault anyway but thank you for all the feedback i would be happy to give you more feedback on your game if you would like.
I just wanted to say its crazy how you got your game running in the browser with all the moving people and effects
