It could have done with better instructions
I completely failed at my first try, and it wasn't until I looked down into the comments that I realized that you weren't supposed to simply jump over everything. I know you left instructions but they're very unclear on what exactly it is you're supposed to do. The last two rocks also looked a bit too similar so that was also confusing.
INSTRUCTIONS
For those with the same problem-
In level 1, press up for the ^-shaped rock and down for the V-shaped one.
In level 2, same for both rocks, press left for the W-shaped rock.
In level 3, press right for the small stone.
After you get that, the game is very easy and a pretty good time killer, very good for less than 72 hour production. The music is very good and the art is surprisingly fluent and pretty.
