1. Place gates
Move your character with
WASDor the arrow keys. Your
character can place and remove gates, which will connect to nearby sources
and other gates.
- Q
- Place gate
- E
- Remove gate
- X
- Toggle gate (either place or remove)
As you move around, there will be light gray highlights that show what
toggling the current tile would do.
2. Mix sources
Gates can have multiple inputs, which will be XOR'd:
| Input 1 | Input 2 | Output |
|---|
| Off | Off | Off |
| On | Off | On |
| Off | On | On |
| On | On | Off |
In order for two gates to be connected, they must have different patterns
when placed.
3. Fill patterns
The play area has unfilled light gray patterns, which will fill up when
connected to a matching gate. Each filled pixel scores a point, and the
pattern will change and move once filled.
