The first documentation for Space Hotel ltd was just a single whimsical board with a few ideas on it.  

This was actually the only documentation before I started building.  It's interesting to look at what did and did not survive.

1. The stored objects in the game all ended up being abstract (no bandages, just safety)

2. Much less emphasis on picking the module.

3. The core interaction of picking an airlock to place something is still there and you do it repeatedly and it is fun but it is now always paired with picking what you launched.
