Like the other commenters have mentioned, this was a hard game to figure out what to do. I didn't realize I needed to move onto the little "window" thing (the scanner I guess) so I was just messing around in my own DNA window. I tried to walk through the door with every possible permutation and almost gave up until I just started walking around randomly and hitting random buttons, lol.
That aside, the concept is SUPER cool. It can be a little tedious to go back and forth from the scanner menu to the DNA menu - but if you converted the "scanner" part into just needing the proper DNA sequences (to unlock, for example, the ability to walk through walls or ice resistance etc etc) so that it feels like you're actually stealing DNA and adapting yourself to solve puzzles, I think you'd have an incredible game on your hands.
But as-is, once I figured out how to play your game, I still had a lot of fun with it. Great work!
