Thank for the comment.
Indicator for when close to the crystals is a great idea, I consider implementing that in some way. Also the area is a bit to large I agree, Ill take a look into making it smaller later. I'm glad you liked the linking of bombs, I was quite satisfied with that feature. The level layout was smashed out in a day to make the game playable, I would like to have had more time to scope it better and make it more coherent with the rest of the game. Trashing the initial room is an interesting idea. Thanks
