Blit's Game

A prototype of a puzzle game, made to resemble the kind of planning and calculation that Blit Bitkin does regularly.

Rules:

• Each gem represents a number from 1 through 9. The same gem will represent the same number anywhere in the puzzle. Every gem will appear in the main grid at least once.
• There are only nine gem types; the shapes and colors always correspond the same way, so don't worry about seeing anything unusual there.
• The goal is to make each row and column sum match its target. You'll know you won when all of the sums are green (this is still too much of a prototype to have any actual celebration on-screen).

• Arrow keys move the cursor around the grid
• 1–9 to place that digit in that space
• 0 to clear the digit there
