Disclaimer: I'm not a big fan of hidden mechanisms myself. However there is one aspect of the "Step" series that is constant in all levels. This aspect is the start. Spoiler: How to start There is a door you have to open to let R beggin the level.This door opens from right to left.
Nice ending to the series. Spoiler Dropped one star for the awkward squeeze push, but still very good overall.
Thanks for your reviews @Don G Rowe and @PvB. I will try to improve my building skills in my next levels!
Yes, a little hidden, but not too hard to figure out. Nice R puzzle using the mechanism from the original Robo Rally.
