Completely forgot to update the prices on the cards 😅

Here's the real ones:

Ocean Ship Shooter - 350

Square Shooter - 210

Circle shooter - 50 (Card is correct) 

Its cool men but is more easy 

you should put some stronger enemies and evaluate the collider of the bullets and the towers so that they are not loose there

Great job! The card theme seems a bit forced in since the cards don't need to be cards, they could just be buttons and the gameplay would be the same, having some random draw would help!
