i need to add the exchange theme in my game but i don't know how , please help me, the game is "in your garden"
Here are some ideas:
If your game has farming, sell plants for money to purchase perks.
Defeating a boss allows you to exchange one of its attacks with yours or allows you to swap out the kind of bugs attacking.
That's about all I can think of right off the bat...
thanks your reply gave me a very great idea
To add to Conan's comment, there could be some form of time cycle wich changes on how the game behave. I think that would be part of Exchange
