I don't understand the size thing yet either, why it is such a heavy file. Thank you for your nice comment about the environment. Level design took me 1 full day. Especially the lights took a lot of work. Finally, a zombie will chase us in the game. I made the zombie's movements, I made the life bar, but the death mechanic did not work and I broke the others while trying to do it. It would be a mistake to continue because I would enter the last day because there were mechanics such as the main screen, game ending and button door relationship that I still had to do. So 1 day was completely wasted. There are only a few fps edits left from that day. So this game was made in 2 days, that's why it's so short. Maybe if there is a lot of interest, I will make a longer and monster version of the game.
