Cool concept. I agree with the other comment about swapping 2 plants. That would be a great addition for quality of life. I think there are many cool directions you can take this idea. For example, just having the rain come and go in different areas of the room would add a great challenge to the game. Nice work, hope you keep at it.

Lovely art, I love a plant-themed game. A few things I think will make the game feel more intuitive: letting players swap plants' positions without needing to move them to another position first. The detection of plant moving seems to rely on the mouse position, so sometimes, even though the plant sprite is in the placement area, it won't move because the mouse is outside of the area. I think it would feel better if the detection aligned with the plant sprite. Still, very good job!
