Wow, that was SO MUCH FUN! \o/

You control the 2 white DNA Polymerase enzymes on screen. Your job is to complete the DNA sequence shown in the bottom of the screen. A goes with T, C goes with G.
Press the left button (A, CTRL, Fire1) to pluck the nucleobase picked by the enzyme on the left, or the right button (D, ALT, Fire2) to pluck the nucleobase picked by the enzyme on the right.
Known bugs:
- Half the Nucleobase letters have their rotation wrong
- Score is kinda meaningless, it should punish you more when you make mutations
- Score is missing sounds for good and bad move. The code is there and ready for it though.
- I am clueless about aspect ratio and resolution so the Windows version is pretty messed up if you don’t use 1980×1024.
- There’s no way to get out of the GameOver screen (You’ll have to ALT-F4 in Windows or refresh the page in your browser)
- Probably many more
