Hi! I'm registering here to provide feedback. I'll apologize in advance if any of the feedback I ever give gets too back-seat-game-design-y, as I am also an indie developer (though one who as of yet has not been published anywhere, so whatever)
Cars definitely feel a little easier to handle now, yeah! Road traction is better, but there are still a few too many places where my vehicle gets tossed in to the air at weird angles (and, often times, collides with something in the air, like a pipe or a rocky outcropping). But I'm definitely feeling better about this.
The new CPU AI is definitely tons smarter, but that also great helps highlight moments where I'm thrown in to the sky and land in a funny direction. On some tracks, the CPU racers actually started to lap me because I was trying to get a handle on the new controls. That being said, by the time I made it down the track list to Alhatra Wastes, I actually managed to come in first on that race, which I think speaks well of the improvements made to steering.
If I could make a suggestion: I don't like that most of the weapons take a second or two to disappear from the weapon display. Until their icon is completely gone, you can't pick up a new weapon. I found myself holding on to something like a mine and thinking "Oh I should get something else" and dumping it two feet before the next weapon pickup, driving through the pickup, and not getting anything because the HUD element wasn't finished fading out yet. I really want to be able to dump an item and pick up the next one as instantly as humanly possible (or, at least, where it makes sense, like with the EMP, mines and missiles).
I'm also not a huge fan of how easily the blue shell missile can drift in to walls before it targets the guy in 1st and takes off properly. On the other hand, the time I spent in 1st on Alhatra, I got three of those missiles in a row, so maybe it's not the worst thing in the world that they require a bit of finesse and a clean section of track for a successful launch.
Also, I miss being able to double fist items like in Rollcage. By that I mean, like... get two boosts, pop both of them at the same time, and get a double ultra-boost. Things like that. With the way the boost works in GRIP that might not actually be possible, but I think there's merit in the idea of getting two of the same thing and it becoming a more powerful singular version if you hit both bumpers together. But that's at the extreme end of pie-in-the-sky suggestions.
Looking forward to the next update!
