I'd like to start by saying that just like the original, this is fantastic. The visuals are great and, on my mid-high PC at least, it ran really smooth, minus the occassional frame drop when loading a new track. In terms of gameplay and control, it's basically identical to the original Sonic Riders, with a couple of tweaks, mostly good but some less than others. With my prior Riders experience, I was able to jump in with hardly any adjustment necessary and play as I usually do.
All this being said, it's not without some issues. High value trick chains are easier to pull off due to high responsiveness, which is good, but I've also noticed it's very easy to fail a trick chain at the last millisecond by turning barely too soon. It's also very easy to cross the finish line and not have the lap count, due to clipping through the finish line's posts, but I'm chalking that one up to this being a very early build. Finally, the big one, I think the standard boost is just a little too weak for the air cost. I love the idea of being able to extend the boost by holding down the button, but the boost itself doesn't give enough speed to regularly justify using it over drift snaking. Maybe a slight buff to the speed or a reduction to the air cost could help it out a bit and make it more viable to use, but as it stands, I hardly used it.
I'm not really sure how to fix these things, I'm not a game designer, please take my critique with a grain of salt. As is, this is still a fantastic re-imagining of the source material and I'm looking forward to seeing it develop over time. Great work devs!
