Nostalgic fun with no ads

This is so much more convenient to play on the go vs my old DS that doesn’t hold a charge for long. I’m so glad we’re able to get this straight from the app store!

Loved delta since day one, I’m praying for PSP and GameCube support one of these updates! I’d hate to go to Manic just for that.
