The game is very challenging, the swarm of bat(i assumed it is bat) always kill me easily, and the gameplay is fun.
Thanks for playing!
Try planting a lot of plants early to get some money and upgrades :D
I worried that if I made it too easy the player could build a lot and get too powerful so the game would become boring.
Ya once i try that and learn how to use the landmine the difficult reduce a lot, nice.
