I was thinking a while what it is that really bugs me currently with how AVWW plays, its the huge, out of proportions spells and the particle effects indeed.
The real problem is this: you can't tell the hitbox of the spells, because they are not differentiated by BULLET and EFFECT (ie, 2 seperate particle systems) rather they are swirling somethings which is AOK for non-reflex games, like turn based battle engagements, but for SHMUPS (which is kinda what AVWW is) this is really bad.
Imo the spells need to get a lot smaller, more targeted, more "point and shoot" style spells, more visceral and faster but with smaller hitbox.
Also something else that is bugging me is that spells are too "precomputed" they are too large effects that swirl around, those smaller particle effects should be seperate from the bullet sprite (and in fact NOT move with the bullet). In fact, there should be 3 particle systems per spell, Casting, Bullet and Trail, in AVWW these 3 things are all in one which looks kinda bad, and maybe worse than looking bad is that its extremely bad for gameplay AND performance (The amobea spells can actually crawl my fps down to a halt, and i have a fairly hefty computa ;p)
Bad for gameplay because naturally, dodging through large swirling spells makes it impossible to know where the hitbox is
The thing is, i think the spells look nice, but we are playing games and sometimes spells need to be practical and fun BEFORE being nice to look at.
I am gonna make a mockup post about this seperately to show what the real problem is with spells and their effects
So here is my mockup
First this is the actual problem of spells (most of them anyway)
As you can see, most spells behave like this, no projectile, no trail, just the "effect" (theres some that ONLY have a projectile though, with no clear hitbox either)
This is how it ought to be on the most basic level, a noticeable "Spell" container, and a trail
More effect, but still clearly visible hitbox
Anyhow, my 2 ct ;p
And yeah.. i didn't put ANY effort into the spell mockup, excuse me about that
As i can't use the games effects as they are in that grid-setup
