Remember, every red dot level has two exits and every yellow dot level has one, so you can keep track of whether or not you're missing a secret that way. Years after I was done with the game as a kid, I was still having random dreams about secret levels that didn't exist but I could have sworn did because of how great the game was with them. In fact, one time, I suddenly thought of a possible secret years after I had put away the game. I recalled that trick that allowed you to go behind the finish-line and uncover a secret by falling under it with Yoshi and ejecting after passing it, and remembered another level where that trick could also possibly be used (except with a little less clearance). I dug up the game again to try it, and sure enough, it let me go behind the finish line.... but weirdly, no secret -- just an empty screen to the right of the finish line -- I had to walk back to the finish line to complete the level. Pretty much everything that you just mentioned that you found irksome about it Chrono Trigger was actually pretty progressive in this regard-- It let you just walk around encounters to avoid them, for the most part, and the battle system felt a lot more rewarding due to the inherent fun in learning all the skill combinations. It also had the natural/accessible feel of an adventure RPG (even though it wasn't) due to all the battle animations and enemy movements affecting what you could hit.
