@kaliuresis I finally got around to trying version 2.0. Here's a recording of my playthrough:
The key points are:
- Put the levels in a logical order so the mechanics are introduced slowly to the player.
- Make sure when you're testing the player on a new mechanic that the level actually requires the player to understand the mechanic in order to beat the level.
- Introduce new mechanics and concepts as slow as absolutely possible. This game uses very complex spatial reasoning that will overwhelm most people if too many things are introduced at once.
- Add a zoom feature. This way the player can see the entire room at once and zoom out even further to better understand what sorts of patterns the links are creating.
