Final Game Comparison To Concept Document Vision

The final game is very similar to the vision laid out in my concept document but scratched some ideas. The major difference was the hunger and thirst mechanic. I planned to have the maximum health and stamina change based on the hunger and thirst but didn't implement this due to not having much time and would have taken a lot of time to try and implement. Another difference was medkit and bandages. I planned to have the player to press the button to heal either using the medkit which fully heal the player or bandages which partially heal the player but decided not to as it could be overwhelming for players to have lot of controls so I changed it that it's just a medkit and automatically heals you when player collects it. I planned on making the world bigger but size of the world in my game feel appropriately sized for this type of game and also planned that they can go inside houses and barricade the door to prevent the zombies from coming in and player can jump out of the window to get out of the house but admittedly that was a ambitious idea for the time we have to make the game so that never happened. Lastly, the zombies dropping stuff. Didn't do this as player can get good amount of resources from pickups that spawns constantly around the world so it would not have made much of a difference.  

Feedback Summary

The difficulty aspect of the game, majority says that the game is well-balanced with comments consisting on how they like the constant movement and good amount of resources spawning but I've received feedback on how the player walking speed should be slower than the speedy zombie but slightly faster than regular zombie. I have changed the player walking speed so they are a bit slower than speedy but can outrun them when sprinting, forcing the player to manage their stamina. From my observation, testers seems to have not many problem with the controls and seems to understand what to do in this game. The fairness aspect, all people says it feels fair to play but some say they have little ammo left which is a point of the game, unless they mean they feel there's less ammo at the start of the game. 

The feedbacks I've received for the visuals are that they feel it set the tone for the zombie apocalypse but also suggests improvement on the visuals, such as, make a house more rundown and adding few things to the surrounding. For making the house more rundown, I make the house a bit darker and for the surroundings, I added rundown cars.

I received some feedbacks on some bugs. One that ruins the experience and one that's not game crashing. One that ruins the experience is that they were no longer able to fire, reload  and switch their guns which I have noticed when observing. It is uncertain if I have fixed it but after multiple testing it seems to be fixed. The other bug is that they see white line flashes in the tiles, it not game breaking but can throw some people off. I couldn't find a way to fix it. When watching testers play, I couldn't see any bugs other than what the testers have mentioned. All the people that played this game, say that the game ran really well, ran smoothly and had no issues.
