I started it and didn't find R as it was too hidden albeit I didn't try too hard as I'm not a fan of hidden.
@gmacpro you have to start the exact same way you did in "a small step" - you have to use the same move to free R. @Shroomir Spoiler: How to free R you have to open a door that it's under water. This door moves from right to left.
@ridgerunner I intended this to be a simple level. Just a bit harder than my previous level. Thanks for your review!
Really thought the first one was better. Not especially fond of the hidden opening or the trick move additions. Mechs for releasing blocks were fine.
@Don G Rowe thanks for your review. My idea was to create 3 levels that would increase in difficulty keeping a similar theme. I'll try harder with the next one. However, it is going to have some moments where R will need to change directions since that was the idea I had for these 3 levels.
