Unmark my words I can't do it. It is beatable but you need to be really accurate with your inputs it's almost impossible for me. I might try again after the jam.
So basically you need a setup as shown in the picture. Follow the arrows on left side and drop bombs from the ledge of the block. Then jump from the purple block to the red block, then to another red block and start dropping bombs until you reach the bottom (do this for both sides). Then jump to the last red block and drop bombs. Once you do that, go to the right side and get to the bottom yourself to mine the last ores.
Grey area is optional. Don't break the red blocks. Green arrow is the last one to follow.
