Thanks for playing and leaving a detailed review! Glad you enjoyed figuring stuff out in the game!
We definitely had more plant ideas but decided to limit it to 3 so we didn't overscope. Yeah it was a bit difficult expressing and incorporating into gameplay that the plants also needed the player. We had an idea of there being some sort of energy tether between the player and the plants as a visual indicator but decided against it and decided to go with the color shifting like what's in the game now., but that might have been too subtle.
Nonetheless, thanks for the review and the feedback!
