This game was amazing! Very addicting especially when I was so curious to see what plant I will unlock next. I died on wave 14 as my defense gets rammed through by those fast enemies. I really love how you introduce the wall plant by first showing a enemy that can shoot and then providing a counter to it next wave. This game looks well polished and the music and sound effects complimented the game perfectly! One thing I would suggest if you want to continue working on this is to have the coin pickup sound stay at a low volume when picking up all at once, as when I picked up like 10 coins at once the sound became very loud. Overall solid game!
