Free Game Prototype: Portals thru Dreams

About a month ago I decided to do a free game. I’ve been thinking about Graduate Games next full game for awhile now, but have been indecisive. I stumbled across some abandonware on my hard drive and decided to explore the gameplay mechanic a little more and release it as a game prototype. I spent probably around 48-72 hours making the game and found it refreshing to limit myself from adding other baddies, graphics, and features.

Portals thru Dreams was inspired by Valve’s Portal. I played portal for the first time over a year ago when the Orange Box was released. It inspired me to attempt to adapt the gameplay concept into a 2D platformer. I got it working ok, but later abandoned it. I picked it up again to use as my first free prototype, but drastically changed some of the mechanics.

The original abandoned version had a pencil/sketchbook art direction and involved shooting a portal with a gun (much more similar to Valve’s Portal). The stick figure sketch guy also had a wall jump/slide ability similar to MegaMan X which made him way too mobile. The biggest changes for this new prototype are the mouse controls and the new Dream theme.

Portals Thru Dreams


Download and unzip the contents to c:\portalsthrudreams\
Launch the exe file
The goal is to collect remnants of your memories and return them to the exit gate. When all your memories are recovered, the exit portal will open. Your goal is to exit (press W on the exit) before time runs out.
Load – opens a load selector – pick levels from \data\levels
Play – Plays the loaded level
Edit – opens the level editor where you can make your own levels
You can move through the world with the A, S, D, W keys. Create portals in the world by left clicking and colliding the shot with the background. Touching a portal will transport you between the portals. Portals keep your momentum going, so falling into a portal will shoot you out the other.

    Excellent visual style, fun, but too easy. Good basis for something that could be tied together with a story and some harder puzzles.

    thanks for the feedback…especially about the programmer art.

    I certainly have ideas for some baddies that would make things a lot more difficult.

    Perhaps this is something we will come back to.
