From the article;
"The most ingenious part of the game is the combat system. Chrono Trigger uses an Active Time Battle system. It’s a great combination of Turn Based and Real Time combat giving you both detail and fast paced excitement. Each combatant has a time bar that must fill before they can carry out an action. Higher levels and speed upgrades allow your time bar to fill faster, while magics like Haste and Slow can temporarily change its pace. The combat keeps you on your toes. If you spend too much time deciding what to do, your enemy’s time bar will fill and they’ll get another attack. Once your time bar is full you can attack, use items, or use tech which can be magic or special moves. There are also combo moves called double techs and triple techs which two or three characters can use together. You acquire these combos when certain characters spend enough time together in combat. This adds extra replayability to the game if you want to acquire all of the combos between all the players. The tech animations are exciting to watch, but never slow the action down like they do in some of the Final Fantasy games."
