Right direction

Spoiler: VS

I tried to make a trick level out of this, but I removed tricks as many as I could. The right path is logical, only B push is necessary and that too only when it is alone.

The level design and atmosphere are very nice. It's a pleasure to be in the level, and I really enjoyed it. The gameplay is interesting, and it's probably a good thing you removed the tricks; I liked the logical solution. Thank you.

P.S. I watched your video and discovered I was directing R differently. The logic for the first part and the first star is the same. But I think there are several ways to direct R to the second star. It's actually interesting and doesn't significantly affect the overall logic of the level (in my opinion).

Haha, I did the latter part yet in a different way.

I did do a dual push. R can step on B at the first little slider B ever enters in the level.

I like the symmetry and the logic of the level. There are many possible options the figure out a narrow solution through.
