It keeps the player quite involved for a clicker game! I think you can even expand on that idea by adding high score times for hitting various milestones. 

The dynamic size comparison is a nice bit of visual feedback. More than anything I would like to see the creature change as it gets bigger, maybe with different final forms based on what you fed it or how fast it grew.

just thought you might want to know i never closed this and

You have 2.35e43 Kg (2.35e40 metric tons)
Height: 4.08e9km (2.53e9 Miles)

Oh! He big

It's a good implementation of the whole incremental gameplay thing (number go up, yes) and the theme is fun too. All incremental games sooner or later reach the point where things 'grow' out of control, and this one has some interesting context, when you consider what that means.

incremental :)

never expected to see a modding tree game here, and one that requires surprisingly active gameplay at that

It's nice! I got lorj

this was pretty cute! i liked the inventive names of the food and feeders, the gameplay loop of buying each type, and the exponential growth!

Pleasant and short idle game, which is not even especially idle, since going as fast as possible requires constantly active juggling.  I actually really dig how that works out, and how I have to keep readjusting what I'm focusing on as things become less effective.  The ol' Cookie Clicker is, I guess, designed to run forever, which means constant amounts of massive downtime.  I like the paperclip optimizing approach of having stuff to do for a while and then a clear end state.  (I guess here that would be having eaten the entire Earth.)

I love the illustration slowly zooming out, that's such a good touch.  Also the names of the autofeeders lmao perfect

One bug, I think: I was holding the mouse down on the magma extractor button when I won the game, and when I continued playing, it was still held down.  Clicking it again didn't help.  So now I'm just constantly buying them, forever.  I guess that's okay.

I always love an idle/incremental game. Grew it until it entered the abyss of space.

Aint bad, very fun, would love to see this cute little fella again.
