Quite boring

Too much the same thing. Might be a challenge after a while, but it didn't keep my interest for long.

well...no

I just did not get the point of that game.

You may wanna try adding an instruction menu on the game.

good try.

In a word: boring.

No real reason to play this game. The first round lasted way too long and didn't have nearly enough correct products come through to make me feel like I was accomplishing anything. There were numerous times where I felt like I was sitting there, doing nothing, just waiting for something to happen. That's never a good thing in a game.

One suggestion I might offer is to have the player choose when to advance the lines then reward them for faster times. That way the game moves at the player's pace and still requires concentration and rewards extra speed. The same penalties you have in place could be applied when the player advances with items marked when they shouldn't be or vice versa.
