My little suggestion, I hope you can consider improving the game:
1. I hope to have a boss similar to Nemesis, and players can choose to fight it to get some unique rewards or simply escape.
2. In terms of weapon balance, the shotgun should be obtained earlier to deal with the head spider. The assault rifle should be obtained later, and the positions of these two weapons should be changed.
3. It is better to add a classic close-up shot of the first zombie "looking back".
4. According to the wildlife situation in Vietnam, mutated buffaloes, wild boars, monkeys, crocodiles, and even infected animals such as boss elephants can be added to make the game content richer.
5. The attack method of the head spider is very strange. It touches you and passes through your calf, and you are injured. It should be improved...
6. Vietnamese zombies seem to only like to eat alone... Isn't it good to have a meal with three people? :c?
7. I actually used a lighter to burn a roadblock in the rainforest on a rainy day... :O? I don't understand why this puzzle is so unreasonable.
