Ed is stranded on an alien planet with no fuel.

Luckily, there are lots of radioactive rocks around. All he needs to do is gather them up and bring them back to his spaceship...

Unluckily, you're tasked with keeping his DNA intact. Good luck!

I really love the visualization of DNA replication! I'm always on the look-out for science games, and this immediately drew my attention.

Neat idea, and very polished, very playable game for a game jam.

May I request a feature for a future version? keyboard controls! I think it would be possible to control the entire game by keyboard, faster than with the mouse, to get a higher high-score.

Really cool concept! Kinda hard tho.

Extremely creative concept!


Great game idea and well executed mechanics. One downside from me is that I'm colorblind and I can't distinguish the green/purple pair. They have very similar saturation and luminosity. You could change that or put letters or icons on top of the colors.


Hey! Thanks for your comment - I'm thinking of working on this further so I'll definitely change that if I do!

Hi, I wanted to let you know that I've made the pairs different shapes so hopefully the game will be more enjoyable now!

It looks great now the colors are a lot more distinct thanks for changing that!
