Cool concept, but for some reason at 160s+ the number of virus cells suddenly became 10 times the usually amount and they filled the screen pretty quickly.

713 kills! Lasted 418 seconds, after 400s things get a bit... crazy :p Nice little shooter with a good upgrade system!

When I tried to play the Mac version, it linked to a linux version. Is this a mistake, or are they the same?

Hm, I actually liked it quite a bit. There were a few flawed design decisions-- movement speed is far too low, it doesn't really make sense to upgrade your fire power beyond the point where you can kill a virus in one shot, etc.-- but it's a pretty cool concept. Maybe add in a way to save infected cells too, so that it isn't an unwinnable game.

Oh, and the Pepsi Consultant line at the very beginning was an awesome touch. I laughed out loud at that, and that feeling carried through the whole experience.

Beyond a certain point, upgrading anything other than firing speed seems a waste of resources. It seems like you only ever need to upgrade damage once. Other than that, fun little game!

Very fun. Probably spent the most time on this game!

Mother of god. These infectious cells are so stupidly fast! Got to ~400 seconds, then the enemies started to speed up exponentially. One thing I don't understand is why the game starts so slow, that it seems to be lagging. I don't really know if that's the case, maybe because red healthy cells consume more resources than green infected cells...?

I like the game, pretty fun and overall nice. No sound, but it's fine, I think.

Simple yet addictive, kept me entertained for a long time.

Very nice shooter, but the character snowballs much faster than the enemies can manage, also, annoying horde bug is annoying

It runs terribly slow for me :(
How is that possible this is only bunch of simple objects. You did something wrong with optimization.

I went into this a little bit skeptical from the screenshots but it actually ended up being pretty fun! Nice!

I guess I lost the fight :( Poor, me! I like the game, but I could had have a bit more power! Even though you have powerups, which is very cool, you could have think of make the 'bullet' a bit more visible. Good job!

Cool variation on the standard twin stick shooter. I like that the world took damage rather than the player.

Somewhere at like the 270s mark the screen just suddenly filled with highspeed badguys and seemed sort of impossible to overcome. Something neat to do might be having your white blood cell change the yellow blood cells back when they collide, making the movement speed level more useful than just allowing you to pickup DNA faster.

Good work, fun game. The upgrading is a nice touch though the damage upgrade isn't so useful after a couple levels

Tested this game on a slow computer, Unity launcher defaulted to native screen resolution with no options in the drop down to change it. I assume this was intentional as in all other Unity games I have played, there are at least 480p-1080p options available. Because of the high resolution, I was not able to play this game without playing at 5 FPS. I am not rating this game because I don't feel as if I could reasonably play it. Please do not lock your resolution. Not only was the game unplayable, because it was native resolution the UI was off the screen. The only solution to fix the UI would to be to play in fullscreen, but that would only make the game perform worse. While it is true, the computer I am testing on this is crap, there is literally no reason to lock the resolution.

was more fun when I found you could move :)

Damage upgrades were kinda useless after about level 4, because I was one-shotting enemies already, which was a little sad.
I really enjoyed the steep ramp up though, it was a wonderful moment, even if it was probably some variety of glitch. I also liked the "health" system of the game, with an invulnerable player avatar and helpless "civilians" to protect. I started off making sacrifices for the greater good, then focused all my efforts on the last survivor.
All in all quite fun, and honestly much more so than I anticipated.

Reminds me a lot of 'Zombie 4' though here the enemies and NPC don't react to eachother, which is a bit of a shame. It makes it hard to choose strategically who to 'save'.

The concept is interesting but the early game is really clunky to control, the 'toy' isn't much fun to manipulate until you've upgraded it a bit, which is a problem as a lot of people might not stick around long enough to find that out.

Oops, I posted before finishing writing :S

Good job anyway, this game is a game which is game-y, I hope you'll stick around and keep making games ;)

I thought the horde provided an interesting game mode. As soon as that happened, I found a small cluster of remaining healthy cells (or even just one lone cell), sat on top of it, and fired rapidly in all directions. It does probably make a lot of the best times incredibly similar though, since most people will make it to that point, and then lose within a narrow range of time.

At first I didn't realize that my unit could also run into the infections to kill them, so I was carefully avoiding them and worried every time I went to the edge to grab DNA. The end-game horde was also less interesting within that mindset, as I could no longer pick up DNA or run to the remaining healthy cells. My end-game play style thus changed when I figured that out. But early game hardly mattered because my unit was so crazy slow.

I had some annoyances with the evolve feature. As soon as you choose an evolution, the game resumes instantly. So I found myself trying to press the mouse button on the play field *as soon as possible* because in the later stages, every single moment of firing is important. I'm spraying bullets everywhere, and the fewer bullets I'm firing, the lower my average rate of killing off the infection. But I also then had a bad habit of getting the timing wrong a few times, or clicking outside of the window and bringing some other window to the foreground. Having just a fraction of a second delay after choosing an evolution would have made that feel less frustrating.

The evolution menu also didn't update the numbers in the buttons correctly when I had 8+ bits of DNA and did multiple evolutions at once.

A notable visual indicator for where my cursor was could be useful. I was having a hard time tracking by my unit and my target simultaneously, and peripheral vision was almost no help, since my unit, the DNA, and the mouse cursor were all too small for my peripheral vision to care. Visually knowing when I had enough DNA to evolve was also a little tricky.

PORTS: Ports to other platforms can be done after the deadline. That said, the sooner you finish your port, the sooner people can play your game, improving your chances of placing in the final results. For best results, provide a Web version of your game, or a Windows version with no dependencies. Also be sure to rate about 20 games to improve your visibility.

MY GAME DOESN’T SHOW UP: If you can’t find your game, it’s usually because the URL to your downloads are missing ‘http://‘. Fix your URLs ( and you will show up.

MY GAME CRASHES, IS UNBEATABLE, OR I MADE A TYPO: We allow you to fix crash or win condition bugs after the deadline (in a sense, like “porting” to support more players). We also allow “typo” bugs. I.e. A true that should have been a false, a word that should have been a different word, very tiny changes that you would have caught if you had more sleep. We leave this open to interpretation, but generally speaking your game should be identical to the game you submitted. No new features, just things you messed up last minute. Typos.
