The e-LAB-o-RAT

If you have the strength to pardon the pun you could play my level. A word of warning, this involves dropping objects on faith plates, something that doesn't always work the same way twice, to counter the annoyance of getting a ball/cube dislodged in somewhere unpleasant all major ball/cube drops are summoned in two ways, one of which is a button pedestal you can press whenver you want (after they are unlocked) to respawn props.
