Gotta say, love the game, its honestly great! But two things that seem to jump out that cause frustration is the check point system and the timers on easier customers. The former is a lesser problem but still frustrating as if you fail a section of the day, you have to play through both the entire previous section and THEN the length of the next section to unlock the checkpoint. Frustrating but not game ruining. The latter however can cause quite a bit of frustration. Say you get two of the highest tier customer in a row and just after them a very easy customer. By the time you reach them, you might have only a small fraction of time left before you fail as their timer is significantly shorter than the harder customers. Bar these two problems, the game runs great, its fast paced, gets your brain going and the art is just fun and once you get the hang of things you can get into a real flow state.
