The first phase looked fairly easy. But then it turned to the second phase and all I thought was "Nope, not this one, count me out."
Second phase is pixel perfect dodging and I HATE pixel perfect dodging because you have to, well, be perfect and doding and are not allowed to make a tiny mistake. Older bosses at least had wider gaps, so even if you moved a sliglty the wrong direction, you still won't get hurt. Combine this with the fact that all bosses drag awefully long and you have pretty much a dead end for people like me.
Also, as if two stages weren't enough, it dies, i creates another phase. I guess this is kinda it's thing to surprise the player? But please make phase two easier, there is nothing worse than pixel perfect dodging.
It's not pixel-perfect.
Firstly, that'd be too much for a mid-game boss that isn't on the game's highest difficulty.
....Secondly, I'm too blasted lazy to make something like that. Making a normal boss pattern is hard enough: But making one that takes that level of precision? I've never even tried that. I know of very few professionally-made bullet-hell games that go so far (which is to say, I know of exactly two of them).
Most games of this type eventually pull something like this: The "that looks impossible" boss that then has the player going "Oh. Well I didn't think it'd die that easy" sort of thing. Phase 2 is just meant to be intimidating. Notice though, I only get HIT on phase 3. Phase 2 is easier than 1 or 3. Like I said, more bullets doesn't equal more difficulty. Now, if I were doing strange things with the angles of those shots... that'd be different. But they are straight-fire shots from a single origin point for a reason. The only thing you need to keep in mind when fighting this boss and doing that phase is "hold down the slow-move button".
....Also keep in mind this is AWHILE from being ready for anything. A good couple of months. These bosses and enemies and items and gizmos and cool stuffs are all going to be getting tweaking/testing between now and then. We're going to have a lot of testing to do. If stuff turns out to be balanced incorrectly, it gets changed, same as always. If you can take down bosses like Centrifuge on Normal though, you can probably handle this dude without all that much trouble.
Besides, along with these monsters will be coming new tools for the player to use against them (which is where the expansion will get INTERESTING, yep).
