this was a nice game even though I am always confused by these types of games controls and the atmosphere reminded me of old resident evil type of games.
gameplay was okay would have loved to see some guns or different types of enemies but considering it is a game jam it was good. I liked that you had to go back for the orbs and then back again to the room with inserting the code at the end. I also loved the puzzle in the beginning very simple but felt rewarding none the less.
some bugs that happened included me getting stuck inside of a wall in the room with the heart and brain painting or screen thingy.
and there were instances where the zombies got stuck in walls other than that it was solid and I would say it is not bad considering you have a saving mechanic.
overall great job.
