Thank you for the detailed critique, I really appreciate it!
I agree with you, tho we wanted the feeling of walking in the darkness and expolring, it can be confusing.
We'll definitely try and make it better, if not with lights and visual cues - with better level design and audio cues.
It was indeed stressful, we were building a better version of the game, but we didn't succeed in time so we upoaded the backup we made.
Thank you again!
