You should probably put up some pictures of your game. Few people are going to take a leap-of-faith.
That was really good! A bit janky at points, but the mechanics are solid, the story is intriguing, and the art is stellar! I usually wouldn't like the non-variable jump, but in this case, it's very helpful that the jump is always the same height, as it makes pulling off rotation and depth maneuvers easier.
I do wish there was a way to indicate that a block is "behind", just like when it's "ahead". Maybe like, a square border?
The words in the dialogue definitely need more space between them.
The resolution is wonky and a bit too big.
Sometimes, when I activated a dialogue, the character would start moving in one direction and not stop.
All-in-all though, great work!
