Hey, no problem! I'm happy to offer constructive criticism (especially if it means the game gets better!)
Tabs would be awesome and I think a great way to save space.
I never did try to click the Engineer, so that's why I had mentioned it in my previous comment. After I had beaten the game once, her character art was in color instead of black and white so I was certain I had unlocked her. I was afraid I'd end up losing all the good stuff I'd built up already so I didn't try a new game. Speaking to that, would it be possible to have a few save slots instead of just the current game you have going?
I'm on Discord for voice acting projects so I have no problems joining your server. I'll do that now and leave these comments here. Thanks for your hard work!
Edit: BTW I just wanted to mention that I can't speak to anything regarding Viruses. I actually never died and had to gain one XD
