7 Segment Display Puzzle

After having to figure out how many pictures were left in a polaroid camera with a broken display, I realized that that could actually make a fun puzzle.

You're goal is simply to pressed the number on the left and hit enter. easy enough

unfortunately, between 2 and 5 of the segments are broken and will not turn on.

Use the arrow keys to either add or subtract one from the big number to deduce what it is.

Press enter to confirm your guess and reveal the answer. Pressing enter again randomizes the number and gives you a new set of broken segments.

Besides improving the visuals, I also want to add a notepad for players to write or draw in, options to pick the minimum and maximum number of breaks, and maybe some other displays
