Nice, an idle game in the vain of cookie clicker, clicker heroes and the like.
It's a fun genre to explore and I like your genocidal theme. Graphics also look nice and clean, music is well done, too. Could use some more crazy perhaps, assuming that your take is as humorous as I hope
It lacks quite some in the signs & feedback field though. Only a healthbar moves when I first interact with the game (not a fancy one either). Takes a second to make that out, in fact.
And progress through my upgrades is slow. If those upgrades even do anything at all, not sure, just assuming I understood what was going on.
Clicker Heroes is actually a good example in terms of juicy feedback (among others): character hit animations, particle hits effect and palpable progress on the enemy health. Actually, why such a modest healthbar? It's your main feedback device, pump it up!
And I feel there's a lot I'm not getting yet:
Why do switch planets at all? And are they changing size upon switching back and forth? Not sure, cos there's not much to recognize them from, names and visuals are somewhat faceless.
Where do my 'troops' come into play? What am I 'creating'? What's the 'knowledge' doing? Can i depopulate the same planet over and over?
Your metaphors might use some explaining if you don't want visualize them more explicitly (which I'd perfer).
Guess I'm coming off a bit abrasive here, let me say that I like what you're out for. This can be good, keep at it.
Short version: needs more responsiveness, I guess.
