I LOVED the concept.
It's also very well executed, from the intro screen, to every little detail.
Music and graphics are great. And you actually managed to pull many games into one here, in a week! so it's an outstanding achievement.
I felt that replaying the 1st level after loosing was not the best fun, so I',m glad you moved me to the next one after a few losses. But that didn't happen to me with any of the other levels. So maybe there's something to improve there. I definitely would at least consider switching the first level for a different one, since I almost churned there.
Congrats on an awesome concept and great execution!
Maybe give a try to my game if you can :)
