I had actually planned to always give blocks some advanced use, agree they should never exist entirely as an obstacle, one idea I had was to have them pushed into water, perhaps either to use as a float or to sink and form a shallow walkway, another improvement on them compared to before is that they move smoothly rather than one tile at a time.

The laser is hardly random, the solution to avoiding was purposely part of the solution to killing the subsequent baddy, plus motion sensors fit in with stealth.
