Thanks for playing and giving feedback!
I have watched your stream now and it was very interesting to see someone play it. I think so far you all nailed it as the level being to large as my scope issue.
I consciously rejected having a mini map in this jam cause I wanted some kind of disorientation, but I think that it did not turn out the best. I still think I don't need the map, but it would have been better to have some kind of indicator of distance to the crystals. I also intended it to be 4 different biomes with different action and enemies, but did not have time to implement that and instead it got a bit to repetitive. The map I planned to place at the wall as a painting , but got the "bright" idea to place it on the rug as an Easter egg. Maybe fun but not that clever.
The flickering of the light does not happen on my machine, don't know if its a high end/low end issue or not. I did have it happen when running the game from unity editor, but not in the builds. So I didn't it would be an issue.
EDIT: I have found the issue of the flickering. For some reason having the light as a child to the player removes the flicker. I had it so the camera was a separate object that set its position to the same as the player and when doing this for some reason it generated the flicker.
Thanks!
