Bloxors is a great puzzle game. Play it between neural recordings, behavioral training sessions, when you take a break from writing that paper and when the reviewers make you mad.
The fun in bloxors comes from the fact that your footprint (how many floor blocks you block occupies) varies with the moves you make. You start 'standing up' and must end, standing up, over the gap, so you fall in.
You must aim, therefore, to be 'lying down' next to the gap, with your footprint in one of the four cardinal squares (North, South, East or West), radially, such as:
Work backward from such configurations in terms of rolling or tumbling, till you get to your current starting point.
This puzzle has enough degrees of freedom and enough constraints to make it fun.
The teleporter adds some spice, though I think it is an unnecessary complication.
