I liked this one. It took me a minute to understand that the gameplay was modeled after Sokoban and kind of wrap my head around that. But it's a neat little puzzler.
For critique, I would suggest changing the art style a tiny bit. If you give the 'solid' blocks a small bit of depth by drawing a darker color along their bottom and right sides, it would make the gameplay more intuitive.
I couldn't find the Armor Games version you mentioned this is inspired by.
