Ren & Jill: Hay Dash

What is it?

It is 8 a.m. and Ren, the boss bunny, has overslept! With his assistant Jill he races from his home to the station, onto the train, through the office and out to Tokyo sights in the evening. Grab the hay (a rabbit’s staple food) along the way, dodge everything else and see how far you get.

The route changes every run and you choose detours at forks. Each season brings limited-time hats and decorations.

How to play

• Swipe left/right (arrow keys ← →): change lanes to dodge
• Swipe up (↑): jump. Swipe down (↓): slide
• At a corner, swipe the way the arrow points
• Eating fills the munch meter; when it is full you get a munch fever (crash-proof, double score)
• Food that is bad for rabbits (chocolate, for example) makes you woozy: check the food book

There are missions, a stamp book of Tokyo sights, a food book and a shop with hats and ties to dress up in.
