At first glance, I thought this would be a repetitive tower "escape" game.
But when I started to play it and go through all levels, I changed my opinion and I had a really great time playing it. It is pretty fun to play and feels like a creative puzzle in which you need to find a proper solution to let everyone survive and go across the traps and towers. So I was wrong and this game has proven to be really interesting and fun!
Congratulations for your good work. One thing I would add is a progress count of the survivors.
