My highest is around 14k. Good game all things considered
The presentation is pretty cool. Always love to see 3D and 2D assets mixed together, and this does look amazing. Especially love how a lot of the spritework actually looks 3D because of it's shading etc. Audio was also adorable and pleasant to listen to.
That said, while I think the game looks great, I don't think the visuals really work all that well in terms of functionality. More often than not, I had to squint to see anything upcoming. It also didn't help that the colours of most things like the pickups and hearts effectively had them blend entirely into the background. I think they could've contrasted better with the environment, like how the bullets shot by the cops atleast contrast pretty decently. That combined with the low resolution meant that I really couldn't see a lot of objects up until they were right next to me.
Might just be a skill issue, but it was definitely my primary problem with the game. That and also there were numerous times where obstacles were spawned right at the point where you take a turning, which meant that I couldn't really react or see any of them until the turn happens and I get hit.
All that aside, when the game does work, it feels extremely satisfying. Rail grinding and doing tricks with those powerups was fun as heck and the environment always looks amazing regardless of my issues. Great work here and kudos to all involved
