• dragging to pan the map
• click a tile to place something
• click and drag to place many things
• click an drag to place a box.

I need to be able to freehand draw, interactively see the progress, and keep an undo history.

• need to track every pixel that got drawn on

• need to draw them in real-time.

• once mouseup, need to keep a history of the entire drawn set of pixels and their previous values.

So once mousedown begins, start checking for pixels. Every time a pixel is being drawn that hasn't already been drawn, add it to the "drawn" array and add "previousValue" to the drawnArray.

previousValue is a number (enum mapping to tile) drawn is a number (enum mapping to tile)

• Show the missing upgrades greyed out. I'm thinking like analog indicator lights. 8 total. 2 columns.
• Show empty minimap, top-right. It should be especially large.
• 1:1 ratio viewport.
• Editor becomes a separate thing you can tab into. (Is it a separate browser tab?)

• Higher resolution viewport
• Sounds
• The Minimap (an upgrade that you can get multiple times?)
  • Lidar only
  • With history (ie. what blocks you've seen)
  • with texture? (ie. before it's just filled or not... then there's textures)
