I already beat 50 levels before the change. But I am not showing the completed badge, even though I have a checkmark for 50 levels completed. Do I need to finish it off again?
Nice game, I love games like this, and this one is well done. But there's no need for keyboard movement - you could just use the space for bombs and the mouse for movement.
I gave 3/5 because it gets boring pretty quick. But good execution and gameplay. Once you get to the stages where you always have 2 or 3 customers waiting, it is impossible to get above 50% on the waiting part for them.
