Touching the bombs gradually reveals the actual map, but also gives you less time to capture the flag. This idea fits very well with the jams topic.
I think the idea of making the maze dark was very good. Therefore it is not that easy to capture the flag and you have to remember the structure of the maze.
Unfortunately, at the beginning i didn't quite understand what i had to do. A small tutorial would be helpful.
Overall i think this game is very well made. Great work.
