I finally added all the enemies with all the point values!

Ladybugs = 25 points

Very basic enemy just lunges at you. They die in one melee hit.

Bee = 50 points

Basic range enemy. The projectiles hurt but are pretty slow. You can also reflect them back if you melee the projectile which seems to be the case with all projectiles in the game. They die in one melee hit.

Fireflies = 50 points

These guys run up at you and explode. They make a sound. When you melee them you fling them in that direction too. They can blow up other fireflies.

Centipede = 0 points

Yea so turns out they give 0 points. They give a crap ton of health back though because each segment gives health. You'll want to save these guys for when you need to heal but they do do a lot of damage and are really fast with without segments so you'll probably want to finish them off.

Spider Eggs = 25 points

They spawn every once in a while and then spawn spiders. Don't give a lot of points but if you think you won't be able to handle the spiders you kill the eggs.

Spiders = 400 points

Spiders are a big threat hey do a lot of damage and have a huge leap and are also pretty quick. They take just a little more than a melee strike to kill so they aren't too bad. They also give a lot more points than the eggs so it could be worth letting them spawn.

Slugs = 100 points

These guys give decent points for when they end up coming out compared to the other enemies. They also deny the important resource of space. These guys are high priority targets. The ooze hurts and restricts your movement which is very bad.

Hive = 1000 points

These big hives have a lot of health and shoot homing projectiles. You can do big damage by reflecting a bunch of there projectiles back. Using the blood shot up close can kill them instantly. As long as your close enough the blood shot should kill them. Eventually Hives with Tapeworm tentacles will spawn. I don't believe there different in any way they give the same point values and don't seem to have more health or anything.

Red Beetle = 100 points

Its like an upgraded version of the beetle. They act the same but have more health. They have a little more health than a melee strike now so you'll need to deal more to deal with them.

Tapeworm boss = 5000 points

This guy is big and scary looking buts hes not that bad. He drops ton of little enemies that are annoying. If you just jump on its back and destroy all the red orb things he dies. The tentacles on him are hitboxes so try not to touch them when you jump on it and when its moving around. If you stay on his back standing still for too long (which too long is like 2 seconds) spikes will spawn under you and damage you so keep moving when your on him

Tapeworm minions = 0 points

These little guys that the tapeworm spawns give zero points. They are also really fast and annoying so the tapeworm should be focused. They all go away when the Tapeworm dies.

Mosquito swarms = 400 points

These guys are annoying. They fly way up high and shotgun projectiles down at you. Its really annoying and they do a lot of damage and have decent health. You can reflect the projectiles back but because of the pattern it doesn't seem to be really effective. You can tell how low they are but how many mosquitoes are in the swarm.

Wasp = 300 points

The blue guys are just upgraded bees they have more health and they shoot out projectiles that explode. Reflecting them back does not seem to make them explode again sadly. They have more health than a melee strike and unlike the bees don't spawn constantly. they have a spitting sound effect and spawn in groups every once in a while. So focus these guys when they show up and deal with the rest after.

Black Widow Egg = 50 points

Egg for the Black Widow more points than the normal egg. There kinda reddish and appear around the time the two Flatworms spawn.

Black Widow = 1000 points

Gives a lot of points but is scary. An upgraded spider with the spiders already being fast there now faster and have more health These guys mean business but give out a lot when you kill them so its a give and take. In the later waves they basically constantly spawn so try and keep down there numbers a little by killing some eggs.

Rhino Beetles = 250 points

These guys are pretty beefy. They have quite the health and damage. The spawn right before {Spoiler}. They are even beefier beetles than the red ones. They give a lot of points though. Don't underestimate these little guys.

God = 15000 points

OH MY GOD THIS GUY IS HUGE! HES SO FREAKING BIG OH MY GOD. As the name implies this guy is a monster. He'll destroy a pillar and start shooting a big laser down into the arena and will sometimes slam his big claw down. His mouth Tentacles will also do contact damage like the Tapeworm tentacles. You have to jump on his back and kill the crystals on his back and on his legs to kill him. When your on his back you'll get shot at by projectiles and attacked by ticks.
the projectiles are pretty slow and the ticks die to one melee strike so just be careful and you should be ok. the Crystals break to one demon shot and if you line it up you can shoot multiple. As he approaches the arena you can destroy some of the crystals with the demon shot before he even arrives.

Ticks = 0 points

These guys give 0 points die instantly and don't do a huge amount of damage. They honestly just aren't that threatening.

So this was just some basic information I got from playing and some testing. I'm not the greatest but I wanted some info on this game and I couldn't find any. If anyone has any more please say so. If I got anything wrong too please say so too.
