My biggest complaint here is that there were two separate occasions that I didn't notice there was a breakable ceiling above because of how the short the screen was. Once after checkpoint 06, I didn't see the shortcut back to the central areas and ended up backtracking all the way through 05 and 04. And again when I missed the way to the flight upgrade near 10, I threw my head against both the updraft shaft to the left and the teeth tunnel to the right before giving up and looking at the map.
Second complaint is that the visual effects are too much and make it hard to see, especially in the flight sections.
Anyway, I thought it seemed familiar, and of course, I remember Radiance Hearts and my complaint about the rotating laser attack. Is the "Lumina" sword a connection or a throwback?
