I've had a couple big non-english Youtubers play my game, I wish I knew what they were saying!
It's very possible to beat the 2nd virus! I can do it, but of course I can. One of the issues I've seen is that the game isn't optimized for small monitors. I developed the game on a 1080p screen, and it plays the best at that resolution. If you still have issues, try changing the difficulty, it's in the settings!
EDIT: Also, yes, the game is still in development.
