Great idea for a game. But why is the resolution so small and can't I run the game in full screen? Making a chain of 5 is too difficult. The last stage is just random. I completed it in 105 moves. The maximum reaction chain is 8.
I didn't see the fullscreen button, it's now enabled :)
Last stage is quite random, but it should be quite likely to get chain reactions with 3 DNA, causing a cascade, but yeah, I couldn't really balance the game as I ran out of time
