From Jesse Venbrux, whose name you might recognize from games like the Karoshi series or Focus, They Need to Be Fed 2 is a mobile sequel to a freeware downloadable game that's all about feeding helpless critters to chomping piranha plants. Neat, right? Don't worry, it's not all sad and evil. In fact, it's quite a cheerful mix of puzzle and platforming elements that works really well on touch screen devices.

Trapped in a cave. Laser things shooting at you. Buttons everywhere. Spikes even more everywhere. It's a normal day for our featureless friend in Focus, a puzzle platform game originally by Karoshi author Jesse Venbrux. Ported to the browser world by Joseph Ivie, Focus features over 50 levels of extra difficult action, sticking you in enclosed rooms with all manner of dangers and challenging you to use your platforming skills to make it out alive.

It's a bird! It's a plane! It's a... OW! Ew... is that a spleen? The fifth chapter of the puzzle-platforming Karoshi series is here, and it's one of the best of the bunch. This edition comes with a flying, indestructible, Super Saiyan alter-ego, a dubious power when the goal of the game is to kill yourself.

Karoshi is a platform/puzzle game where your goal is the exact opposite of most such entertainments: you have to die. Throw yourself onto spikes, zap yourself with electricity, smash yourself with a falling safe. It's like an extended version of the cathartic moment when you get finally get sick of Mario's empty-headed cheerleading and just hurl him off a cliff.
