A 2v2 racing game where each team plays as grannies and grandpas that try to escape their nursing home on a wheelchair built for two.

Guests need to control the physical wheels to drive the avatar, avoid nurses and barriers.

Only the leading team can escape!

Designer part responsibility:

#1: Iterate the level size & difficulty so our guests in the festival can enjoy the game in around 3 minutes.
From Interim (week 1) to Final (week 2), make the game easier for more naive guests to enjoy the whole journey of our game, as well as maintain the fun of play I wanted to give to the players.


Level 1

"Tutorial Level".

For guests to be familiar with the control of our game, know what will happen if collide with obstacles & nurses, learn how rotating the wheel forward / backward can affect our two-user wheelchair avatar.


The shorter path is always narrow, combined with our physical-wheels controller and the hard collaboration of two players, I want players with skill & teamwork can be awarded in the racing part of our game.


Level 2

Level 3

This is the last level and the outdoor part of our game.
Feature 1: The wheel that is on the road will move faster.
Feature 2: The tree will fall down and smash the player if the trigger zone is activated by the player. This one is for fun and surprisingly successful, this makes the audience who is watching other players playing this game keep laughing. When the audience & player see the nurse near the tree, they will laugh again. 

​Speed Up & Surprise.

Play safe & slow or 
Play risky & fast?


Whole Level

The whole map is smaller, deleted the repeated part of the outside scene.

#1: Can control the interest curve.
#2: Guests during the festival can finish the game faster.


#2: Use visual components to guide the guests and tell the story.


Using night scene instead of day scene to fit the "Escaping" theme.

Yellow and Green Spotlight for the endpoint in this dark scene is obvious, used to attract the player.

Red Spotlight on the nurse, give the player a sense of "danger".
Players may focus on the nurse first, when they realize there is a tree, it is too late : )

Leading lines and deep space show the endpoint at the beginning of our game.

This is for naive guests during the festival to be able to know where to go.

Using contrast color of winning team and losing team. 

The winning team's post-processing effect is warmer.

The losing team's post-processing effect is colder and twisted.

Producer part responsibility:

Took notes and collected feedback from professors & classmates, made new plans and assigned works. Did retrospective with the team to see what we can improve for the festival.
