Amazing game, but you want to know what's even more amazing? I can understand the game(after some trial and error, (I have edited this reply 23 times) ! It's simple, here's some tips and a small guide of notes I made.
The Spreaders: are basically automatic.
The Purifier: they make spores that multiply any nearby spores but they have to be "full" which means fully grown.
The Enhancer: They give you more spores and place down automatic spores
The Gun: Kills the spider in the first part of the game.
The Spider: It's that little thing you first encounter in the game, and it eats your spores.
Tips:
This game requires you to NOT have OCD and patience, you will not like it if you don't have that and to watch very slow progress be made but be able to see that progress being made at the same time.
The Spores take longer to get full the more upgrades you buy but I also think they give you more at that same time.
When you buy something it gets placed onto the collector it belongs to
You can not buy anything when you are placing spores down, so it may seem like nothing can be afford, you just have to let your cursor go for a little bit.
Everything is color coded and but not all colors are connected to the collectors they represent, in fact it's more of connected to its corresponding collector that's in front of it, and from left to right it gets more lighter.
What could make it easier is to just name everything yourself or to read the first part of each name and call it a nickname.
There are 49 collectors.
Just feed the Spider to make it go away, or, you can drag your cursor across the screen and the spider will follow it, drag it away from the spores.
The Spider's name is Larry.
The Spider doesn't come back after it dies (might be a glitch)
If the spider dies, the lazers are pointless to buy.
