A Dream?

by Chen Yanhao

"A Dream?" is the name of my game. This game contains humour, adventure and mystery elements. This type of game allows you to "create your own ending" by giving you options on each level that take you to various locations and outcomes. The game's lore is that the player passed away in the hospital at the beginning of the game and wakes up as a roaming soul. The player then enters the exit through the hospital and gets reborn as a ancient microorganism and the player must decide which exits they should choose in order to escape the so called "dream" or else...

Starr Hunt

by Lim Enoch

-You are trapped in a part of the cosmos and your rocket will explode for no reason in a short while.

-You have to find a star(the shape, not the other meaning that refers to the sun) that will help you escape. It can generate anywhere on the map except for the starting space.

-Your rocket can only take 5 hits

-Black holes might generate in some areas which will pull you towards them and teleport you back to the start of the map ([0][0]) and at the same time take away twice as much hitpoints.

-Hitting an obstacle except for a black hole will reverse your current velocity (propel you in the opposite direction, ah yes realistic physics);

-Note: the lower your hitpoints, the faster your acceleration

GOOD LUCK!!

Twelve Fifty Nine

by Jia Heng & Shao Yu

It's 2077, there's a high-tech facility "Volt Industries", a power plant that is experimenting with harnessing the power of Earth's spin to generate electricity.
However, the main computers of the facility got infected with a virus, which forces the reactor to heat up uncontrollably.
Everyone on Earth flees to outer space because, well, they can, but also because if the reactor blows, the Earth stops spinning, meaning time stands still.
The reactor is predicted to blow before it reaches one.
You're an agent, perhaps the last person on Earth, trying to fix up everything.
