First of all, I just want to say that the melee system in version 1.13 is a big improvement from the 1.12 version so thank you to the development team for that. I like how it is easier to sneak attack zombies and they are not too difficult to deal with like in the 1.12 version. Also, it was a very good idea to have different type of zombies with certain health points, damage, and abilities to be added to the game. Now for the feedback, I was playing on a public server today and I noticed that when I was being chased by a group of zombies they are able to melee me while I was running away and running backwards, but I was not able to melee them back while running away or backwards. Currently I have noticed that the only way to initiate the melee system with a character is by holding down the right mouse button, and then click the left mouse button. However, the character is immobile while they are in the melee system, and this puts the character at a disadvantage and very exposed to a counter attack by zombies or other players. It is also unrealistic to not be able to move or run around while punching or using a melee weapon. So with that said, good job on the 1.13 update, and hopefully the development team will add the ability to run or move around while in melee mode.

Thanks,
