Hi, I'm sorry for the screen size issue :(. We still don't really understand how the UI works in Godot and we struggle a lot with it.
Sadly because of the screen size you probably also couldn't place the plants in the bottom "bench" area that had 9 slots for your plants to idle in.
We will improve on the game in the future and a UI rework is definitely planned. Hope you will give it another go then.
Thanks for trying it out!
