Hey guys there is no use for the crystals at the moment but there are plans for it.
Not yet. :(
I'm still working on their grand purpose as I hope to make them central to everything that will happen in the game. I'm only still scrapping the surface of things I want to add to the game. Firstly, I want to make sure the game is working (near bug free) for everyone before moving on to the more interesting content.
Hey I'm sure your busy and I'm just some random person but I play your game quite a bit despite its simplicity and I have TONS of feedback I'd like to share my email is SimplyDerp.drool@gmail.com if you would like you could start a chat room, like I said I have SO MANY IDEAS I think we could have a good time bouncing them back and forth (This is not asking to hire or do business with you)
Sincerely
-SimplyDerp
P.S. I also understand not all ideas could be implemented or even if you will accept (I would just have ideas I have little to no programming experience I just have ideas)
