Finally got to playing this, and not a moment too soon. Overall, one of my favorites that I've played so far!
Overall, I enjoyed the whole experience. I guess rather than say "I liked this part" over and over, I'll go straight to my nitpicks.
The dialogue had quite a few typos and misspellings (in English anyhow, can't speak to other versions.)
Gameplay was good overall, bosses 1 & 2 were my favorites. The zoom never really came in hand for me in this one. The quad jump was nice though. The last boss was really hard, but a lot of that was the incredibly frustrating lumps around the edges of the arena. I have a hard enough time dealing with 3D bullet hell, but those lumps just felt like a thorn in my shoe.
I didn't really understand the collectables that popped out of the bosses... were those for score or something?
All and all, it was another great entry in the series! I'm not sure if I liked it better than "Lament on the Brine". Having a fully arena to move in was nice, but there's something about that one that was really cool. But this is pretty close, and if it was expanded I could see it overtaking "Lament" as my new favorite. Either way, really great work!
