The enemies' design were so creepy! However, the lighting is simply too dark and navigation became more frustrating rather than scary as there were moments I could not tell where to go.
Having the contrast at the start so that the player will naturally approach the lit area to see the key and spider which establishes the objective and obstacle is really good! However, after that, it is not clear where to proceed. Thus, players are forced to test the doors one by one and hope that they did not miss a door because they could not see it. You should place lights around areas or doors that the players should proceed to so that they can at least try walking straight towards them even if they cannot see their surroundings.
However, it is pretty good for your first game! Good job!
