Btw., some additional thoughts:
* If you don´t bother about enemies but just run with your blades: the scuttling sound of the spiders´ feet ceases abruptly instead of slowly fading to zero :-(
* It would be nice to be able to walk through the upper floors of stackable conveyor poles - not only on ground level. If you try to fix sth. on the 6th level, it´s a pain because you cannot pass through the arches. It doesn´t add anything to gameplay not-to-be-able to pass through them.
