I think there's a bit of an issue when using two copies of schrodinger's cat? It only lets me activate one, even though it shows the other with the shiny frame as if it was activatable.
Also found out if you activate the ability of Schrodinger's cat and then try to activate Virus ability, it opens the cat, showing an "ability activated" rendering it impossible to use the ability of virus.
Edit: If you try to use virus' ability first, it'll just trigger Schrodinger's cat ability without sacrificing the Virus.
Thanks for the great job of reviving this game and for all the job you're putting in!
