I love the aesthetics! It's simple and clean. Using the neon light to grow plants in a step based movement is clever! I'm surprised how complex the puzzles became with a few mechanics. I got stuck on level 6 but had fun.
One thing I'd recommend is simplifying the controls. I had to move my hand all over the keyboard for various inputs. It would have been easier to navigate the main menu using arrows + space bar rather than enter. During gameplay, it would have been great to have a menu to open to head back to the title screen or restart while having an undo button on a dedicated key closing to the space bar.
Overall, you did a great job on the game!
