Hey!
Thank you so much for playing our game and for your feedback, we are glad you enjoyed it :)
We indeed took inspiration from Limbo for the ambiance and aesthetic, and also a bit from Heart of Darkness :D
The lantern gameplay was a deliberate choice, so the player won't spam it to enter and exit both dimension while conserving the lantern gauge at a high level. Also, while doing this, we found out that it added a certain timing and stress to the feature, reinforcing the puzzle aspect of the game. But hey, there is so much we can do in 1 week :D
