I had some issues getting this to play initially. The Unity loading progress bar would get to around 95%, and then stop. I tried in several browsers and it happened in each. I waited and tried again later with the same issue. Eventually, after several tries, and a hard refresh of the web page, I was able to get it to start.
It feels odd that the truck has a lower durability than most other options.
With there not being a cost to select your vehicle, and one being clearly superior to the others, it feels like you should always just choose the best car.
It would be nice to see how much money you have when customizing your car, especially when starting the game and not having seen the amount anywhere else. I like that the cost goes red when you can't afford the purchase, but I'd still like to know how much I have in advance. I see that clicking on the HUB button it does show the amount.
The game page says to interact with the race via the HUD, but I do not see a HUD. Nothing I click on or press seems to do anything. After the race I got a score, but then the cars just kept racing and I seemed to be stuck.
