Zzzone!

"In space, no one can hear you curse..."

A gravity game loosely based on the famous "Thrust" which I enjoyed as a teenager. The goal is to place fuel pods into a collector so the rocket can lift off. The game starts with two training sessions.

The game is alive at https://www.engehausen.de/jan/zzz.html

Building the game

Make sure the dependencies are resolved by running npm install. Then execute

npm run build --production

to build the game. Open src/index.html in a browser; this will run the game.

Running the game in debug mode

If you run just

npm run build

and then open src/index-dev.html in a browser, the game will contain some additional debug code. A level can be accessed with the prefix d and its code, for example: file://...src/index-dev.html#d77564 - this will render the level and its model. Pressing d removes the SVG layer, e removes the model layer.

Here's a screenshot of the planck model of a level, used for debugging:

Building the editor

Yes, I created a level editor for myself. It is not very fancy, but it beats writing pure JSON. I used it in combination with manual intervention to create the levels. If you want to have a look, set the environment variable EDITOR=y and run

npm run build

Open src/index-dev.html in a browser. This will show the editor. Here's a screenshot:
