If I ever got a virus that whistled at me like that constantly, I would get a new computer. I really liked the different virus mini-games. I would have like to be able to purchase some sort of automation for selling BTC without needing to hold the button down. I spent the majority of the game on that screen, even ignoring viruses and going mad while waiting to hit $1,000,000. I didn’t bother fully upgrading everything. I liked the exchange mechanic too, but it would have been nice to see the price changes be more meaningful. Maybe bigger swings would make me want to focus on increasing my mining capacity while the price is low on exchange and focus on selling when high. In the current state there was really no reason to wait for a better price. Overall a great game, very polished, and I enjoyed it! Nice work!
