Really quite like this one. Feel's like it does something interesting with the theme rather than just making an awkward control scheme.
RN though, I think it falls slightly short of achieving it's potential by adhering to the theme. As is, it's not really much more than a standard "shoot all the dudes" schmup. The core mechanic only really vaguely comes into play at the end of each round, and at that point, since they don't seem to multiply then, there's not really any interesting challenge to it.
I'd love to see what happens if you ditch the theme, and instead have the player try to balance the number of blobs between two numbers. You could probably still have them stop multiplying at the end w/o removing the challenge, though a visual indicator would be nice like them freezing up.
Finally, not really sure about the dialogue, it doesn't seem to have much focus and just feels like arbitrary exposition, which makes me question why it even needs to be there if it's not focused on. At least make it skippable/add indicators of how to skip it.
Overall, cool, I think it just needs more room to grow.
