Super cool idea here with a lot of potential! There are a couple things I'd point out:
If you're going to auto-type out text, I recommend going 2-3x faster than the current speed, or at the very least, clicking should instantly type it out. I didn't want to skip the story but it was a little rough waiting for the text to type out.
I'm a little surprised no one else has pointed this out, but there's a massive abuse of mechanics you can do where if the blobs are next to your towers, you just start to place a wall or something and the enemies will freeze while the towers mow them down. The tower attack speed should be slowed down as much as the enemies are while placing buildings.
Would be nice if placing walls could be done more quickly, like dragging out stretches of wall or at least staying in "wall place mode" after placing one wall.
I also agree with the commenter below that HQ should start with a few collectors by default.
However, that aside, I love the structure and concept behind this game. Awesome job!!
