Nice game, lots of complex interactions with the dice and breeding available early on.
Prestige, however, needs some work. I was able to reach end-of-content on my third play through (plus two failed attempts). For that, I get 25 prestige, nothing close to the 128/512 I need to access the true end-game. So rather than being a continuation mechanic, prestige does nothing but hold me back. Why can't I play to the end if I'm successful so far? Do I have to grind now, even though I haven't had to so far? Why isn't there a "bad" ending, even a one-screen congratz, with a restart adding something new to play with from the beginning? This game doesn't actually need any of the repeatables, except one or two that could be one-offs.
I did like the main game, though, so maybe i'll grind to see end-game content. It's just a pain to be forced to play a game a certain way, especially when the presented challenge is to get as far as you can. If you want people to fail (and prestige) a lot, you have to make the challenge harder but also more compelling.
My end-game (second alien attack):
