Great incremental clicker sim tap-tap idle progression game

Love it, perfect game to zone into. The one game where tapping and idle collections are both robustly designed—two different paths you can take on each level, depending on how your planetary research plays out.

Remarkably tuned, nuanced mechanics and upgrades, and a variety of idle options.

Downside? Research takes a long time, and you’ll need to buy at least 8 scientists to really get things done. I have 10, using 5 to research, and split the rest between nanobots, irradiation, bacterial evolution, and irradiation. The premium cost of speeding up research, as well as a bunch of other things, doubled a couple of months ago. That was also lame.

Content updates could occur more frequently, and perhaps with more significant impact or addition to the game. The updates have mainly been several new supplementary systems, some systems iteration, and fine tuning. Good stuff, but I want more.

Because it’s so tightly tuned with such a great aesthetic alignment of systems, it is essentially a five star game. However, because the prices of things using premium currency went up recently, I give Bacterial Takeover 4 stars. Really 4 1/2. It was an unnecessary price increase.

One Small Issue

I greatly enjoy the game, don’t get me wrong. It’s simple, fun, and quite unique for a clicker game. The only issue I find with the game’s mechanics are the gene strands. Gene strands are used to increase your production and for upgrades. The issue? The gene strand upgrades are much to overpriced, and are often counter-productive. For example; there is one upgrade that increases your BPS (bacteria per second) by 100% when idle, and costs 2500 gene strands. The issue? Each gene strand increases your BPS by 1%. Which means you waste 2500% of your production while only increasing it by 100%, making it a whopping 2400% decrease in production. Which means, for every overpriced upgrade, you collectively lose more and more production percentage. I think this issue has been overlooked by the developers, and should be fixed so that unwary players don’t waste their gene strands on upgrades that don’t provide enough production increase for their massive cost, and so that players who know this issue will have a better use for gene strands other then keeping them piled up. If you have read this, thank you for your time, love the game, and I hope to see improvements in the future!

Thank you for the feedback! The Gene Strand Upgrades can indeed reduce your BPS at first, however, they all become beneficial at some point. You can read more about this on our wiki page:

Cool game

I like games that allow me to leave and come back. This one does and the idea of taking over planets is cool. The graphics are great and the time line isn’t bad either the only thing that keeps me from rating a 5 star is I don’t get how to mutate bacteria. I started this game on another device but it crashed so I am starting over not a problem there because I was having fun only wished I could figure out how to mutate the bacteria.
Thank you for your response, I figured out how but where do you get the other bacteria to mutate?

Update: Oh, I did solve the mutation problem. been away for a bit never deleted the game just doing other things and started playing again. The new graphics are awesome. Keep up the good work.

You can get new bacteria to mutate in the Bacteria Evolution lab under the Research panel.
