The DNA puzzle was super cool! Mostly because I felt like I had unlimited power. I kept getting expansion upgrades, so I always had room to add more. The synergy idea you wrote in the description sounds great; it's nice to have room to just keep adding DNA, but it'd be really satisfying to interlock as many as possible and get really powerful bonuses from planning around the puzzle aspect of it.
I actually really like that you never have to leave DNA behind due to running out of room. That would have felt bad as a player so I'm really thankful for the plentiful space upgrades you designed. It was really satisfying knowing that every enemy defeated made me a tiny bit stronger.
Despite the lack of sound and basic graphics, the design had a really nice quality to it that kept me engaged and wanting to see how far I could grow my character. Great work!
