what the heck is with the last boss? if it's random, game rating goes from 5/5 to 2/5. I'm not someone who rates 1s or 2s at all, but there's nothing I hate more than a boss that, depending on chance, is impossible to beat in some trials...
when I previously reviewed this game I agreed with another player that the difficulty curve was very steep. I take back any negative connotation that may have had! This is an excellent game! However, to the inexperienced puzzler the easy tutorial levels at the beginning may be hiding the true difficulty of the game.
4/5, because there are actually levels that are impossible to win. I love the game, but I highly dislike games where this is true. And no, I don't mean levels themselves. But I mean trials on levels. I managed (by sheer luck) to have both green lights on on level 19 and keep them like that, and time ran out before enough cars came through.
