You nailed the alien planet vibe! The underwater effect for the algae is really cool, and the overall glowiness on the plants in a dark cave makes the player feel stranded in an unknown world.
I liked the remote boat control. It took me a while to figure out that you could only move it while seeing it, but once I got that, puzzles got a lot more interesting and fun to figure out.
The plant DNA sequences in the console felt a big meaningless, since there wasn't any punishment for getting it wrong, and you could essentially brute-force it. It's a cool concept nonetheless, and could very easily be expanded upon. I also got stuck in the terrain too often for comfort when walking around.
I think this game could make a very good use of camera panning when entering the puzzle-areas. It was confusing at times what needed to be done and how to do it, just because there wasn't any overarching view of the area, and I couldn't see a path to the places I needed to be.
Overall, this was an awesome experience! I spent a good half hour playing this, and I was left wanting for more. If you have plans to develop the game further, I'll be more than glad to playtest it and give some feedback!
