It's a interesting idea, but the combat is kind of boring, but also too difficult. I felt like the only way to get past the pits was to sit in the corner and spam the shockwave and power up. I think the power ups are on a time limit for when you can use them, but it wasn't clear to me if that was the case. I also feel like knowing what a power up did would be nice.
The idea of the platforms coming alive and moving seems neat, but currently the platformer sections don't make much sense to me. The first few platforms in the first section aren't tall enough for you to stand on without touching the lava, and I found it easier to just quickly jump through that section.
The sword feels like it was introduced too late into the game, and power up spam still seems better. The infinite jumps doesn't make a lot of sense since it would make any future platforming pointless.
The story was cool, though some of the text was cut off, and there's a bit of a delay when you click to advance so it's possible to skip some of the story.
If the combat was a bit more interesting I feel the game would be fairly solid.
