Thanks for review! :)
I am glad that someone played even the nefarious mode as well, and liked it!
Tuning game play in such short time was challenge, for next time it would be great to have some testers, because we didn't want it too hard not too easy.
Rat spread was limited in total amount, but I guess we could make that even harder so they spawn exponentially and player really can have problem if they won't kill them fast enough - but I was afraid this might make the game frustrating :D
