I got a suggestion. when the battle with 2 or more enemies. you can click attack on their names instead of choosing on their head. This will prevent attacking the wrong monster from confusion which is which if there are 2 or more similar monsters.
Nice game, i have a 2 cent worth of suggestion to give. you are able to pick up weapon when you are using handgun and your reserve slots are full. i hate to use my use my gatling so i can pick up a sniper, when i going to fight boss soon and i want to reserve my better weapons for it.
The knife should have a option to throw or not before the mission. I hate to throw my knife at the swarm while there are still 3 or 4 bugs on me doing some damage.
A restart feature is needed for getting loots. Example if i getting the dove loot which require not to kill any enemy in zone 1. If i accidently killed 1. i should be able to restart instantly, instead waiting to get killed
Actually you can ! In the pause menu, there is restart icon on the right bottom corner.
