just some suggestions if you actually update it
maybe bring back the ghost and magma enemy's that you originally planned to put in the game, the ghost would *probably* destroy campers maybe magma too if it doesn't get destroyed by walls
enemy suggestions
bomb zombie- similar to your game "captain explosion" this guy runs towards the player then blows itself up, probably would to 2 hearts and a half of damage also could blow up wood and cobblestone
Shield zombie- this guy doesn't really have extra health instead he got a shield which you cant just break with your gun you have to hit from another angle this would kind of be impossible because zombies constantly face the player soo just make this zombie turn slower (if you can program that in)
Grenade skeleton- same thing as bomb zombie but faster does more damage (so insta kills you basically) and actually *survives* the blast (on 1 hp) then he turns into a normal skeleton
cold ghost- this is probably gonna be an NIGHTMARE to campers (and normal players too) first it passes through walls and freezes you when you touch them.
poltergeist- another ghost enemy, this guy straight up breaks the blocks it passes through for more enemy's to come in and they steal some of your blocks when they attack you
homing rocket skeleton- shoots homing rockets. and destroys blocks
social anxiety baby zombie- this baby is a nightmare for zombie killers because its self-destruct size and damage depends on the more zombies are around you
judgement ghost-if you add boss rounds this could be a boss enemy maybe one of the later ones basically it does more damage the higher score you have
0-IQ zombie- this is a joke enemy who uh doesn't have any artificial intelligence and just stands there (not a reference to combat.io)
300-IQ zombie- another joke enemy maybe the final boss lol when you get close to him an image of a nerd pops up and u die
i have a lot more ideas but i cant share them all in this comment so yeah
