Welcome to Mobile Monday!
In the first game by Kansho (Saburou Konuma), still holidayish, you find yourself in high mountains locked inside Santa's cabin, When you escape you get to shou harata's snowy island where you face a polar bear who proves to be much less hostile than he seems. Then comes Tasuku Yahiro's orange room which is definitely warmer...at least looks so. Bonus game by Shien is a collection of short and funy escapes.
All games are free and available in Google Play and in Apple Store except the bohus game (for Android users only).
The first three games are medium-sized, the bonus game is a collection of nine (plus one) short games.
