Hey guys! kkoutris here with my first redstone project. This contraption creates a moving 3x3 glass platform underneath you as you walk in the air.  It can be activated by holding a stick in your hand, and turned off by holding a feather. You can move in all four directions as well as jump to go up, and break the middle glass block to go down.

The tnt bow can be used simply by firing any bow like normal.

WARNING: make sure you activate and deactivate the machine away from the redstone, or else you could break it.
Please comment and give and diamonds! THX
