Thank you for taking the time to formulate this nice and balanced critique! We appreciate it greatly! ^^
UI-feedback, yes definetly on the todo-list!
Love your description of the two phases of gameplay, or tempos. We were aiming for that sense of acomplishment you feel after a period of struggles, and you formulated it perfectly!
I'm so glad you liked the art! I had fun creating that 1920s atmosphere, and Robin did an awesome job with animating my sprites. =D
