The grind required for the game so far is much too high. Starting out earning 17-22 coins for each game you are forced to fail. The tubes fill up far faster than you get opportunities to empty them, leading to a hard cap of 4 doses at the start.
Getting juice control doesn't help either, cause surprise, how filled the juice tubes are is directly related to the amount of juice dispensed! You are actively kneecapping yourself if you get juice control.
Getting lights reset for failed inputs seems arbitrarily harsh as well, seeing as the bar already gets paralyzed when you click anyway.
A frustrating game with promise is the best descriptor.
