After a few hours? The game takes off really slowly, there is nothing really to love about the first few hours, it has a slow start.

And no, the normal enemies walk around on screen, so an experienced player can move around them and avoid them with ease. Some of them will give chase or will be blocking a path though- so there is that.

I loved Cross and I loved Trigger. If you quit after only a couple of hours, I highly recommend you try again. It is a great game and the hidden ties and sidestories you can find that tie up lose ends with Chrono Trigger are very sentimental. There is an orphanage scene that deals with lucca and it is just the saddest thing in the world
