Thank you for the feedback! The red currency is still relevant after the green for sure, and those 2 aren't the only currency that will be used in game. Also the initial tutorial mentions that Red Viruses cannot damage you, only red. But yes same for story and tutorials there is in the full game a logs screen with both story/lore and more detailed tutorials. The demo is here mostly to show the gameplay and overall gamefeel, you can reed my reply to Fort Kenmei for more detailed info.
