Amazing art! The character portraits really add to the production value.
Your score caught my attention as well, particularly the final stage. The dynamically switching music tracks worked to great effect and kept the level fresh.
I do have a couple suggestions for improvement: more environmental detail, and maybe a more forgiving object interaction range.
Also, I noticed a possible bug on the first level. If the moustachioed man hits the blue button before the lady, the game treats it as a mistake. Though that's a pretty insignificant detail and I might just be making an error lol.
Really great teamwork, you all! I'm glad I got to experience your game :)
