Quarrel developer Denki has released Save the Day, a frenetic HTML5 take on the Apple II classic Choplifter.

In Save the Day, players have only a few minutes to evacuate hundreds of people from the path of an erupting volcano. While the premise is similar to Choplifter's, the pace is much quicker; you'll have to plan out routes quickly and save multiple survivors in a row in order to earn score bonuses and time extensions.

While your main goal is to rescue survivors, putting out fires is also worth your time, as they often hide point-boosting treasures. It's great fun, and a well-designed upgrade/level-up system makes the experience even more addicting than it would be otherwise.
