What a great idea! I loved this. I'm still puzzling out that bonus coin, must be those after effects you're talking about. This is giving my brain and fingers a pretty good work out.
the hint is that the generator is a wooden box generator. so careful dun get stuck after u get the bonus coin.another hint. to get rid of the boxes in front of the coin..u do not necessary need to destroy the reflector in front.
push the / shaped reflectors int he lava and use the other shpe reflector in parallel to do so.dun forget the box generator will generate(double box) to block your return path. 1st/2nd section needs 6 barrels from the 1st area. 3rd section needs 8.
