I don't know if it's intentional, but the enemy units attack in the same direction as the player units. This means putting yours on the bottom row makes them almost invincible.
I could play this game for awhile though, it's fun!
yes this is intentional, thats why you need plants like cauliflower or garlic to beat them
Hmm, I like how it plays out then!
...except when the enemy starts using the ones that attack downwards, then I get screwed :P
haha yeah, just gotta try and beat them, if the enemy has too many downwards attack you could just always be at the top
