Ultimate Plants TD is a game about dragging plants and dealing with physics while zombies attack. i think the free-to-play model is a bit wonky but still worth a shot.
Click, drag, and win, but the physics make placement feel random.
Clicking and dragging are the main actions you perform. The controls are straightforward but get repetitive fast.
Quick, simple, and hard are words that describe the strategy. Most players find placing a water-type plant near the entry point slows zombies down.
