As others mentioned, it took me a bit to figure out that jumping triggered the rocks. Once I figured that out, though, I was kind of expecting a level where I had to be really careful when and how I jumped or the level would be stuck, but never really experienced that.
That said, this was a cool idea, and I especially like the level where you kind of had to ride a rock down and move it over to get through. There’s definitely a lot of potentially here that I’m sure would make continuing on this project worthwhile.
Nice job!
