Haha thanks Filtrax! I was hoping to expand them with color but I'm glad they got the story across!
Yeah, I didn't realize how frustrating it was until after I submitted, so if anyone beats the full 3 levels in a row I'd be very impressed (I can beat them individually with a few tries, but all 3 in a row I still can't haha!)
I would probably still play the intro again so you can "meet" your new batch of rats each time, but yeah going back to the last played level would be an update I'd have done with more testing.
Thanks for playing :)
