On the race gameplay... coming into this, I was expecting a racing game where you drive the car, but I was wrong. It is quite frustrating when you car just bump into other cars and never overtake them. The only interactions are what looks like a nitro toggle on the bottom-right of the screen and it does speed up your car a bit, but not significant. I also don't really see the effect on toggling the aggressive/lax mode on the bottom-left of screen. The gameplay for the race itself is pretty non-existent at this stage, I hope you'll make some improvements on this in the future builds. More often than not, I get frustrated because you keep bumping into other cars and there's no way to control it out. Or worse, when there is a faster car bump into another opponent's car and pushing the slower car to move faster.
Another thing on the race, if I want to win I just select Porchat and it will just blaze through the race track. But if I choose the truck, I will just always lose.
I can't give any positive/negative judgment on the idea at this stage. It still a lot of work since you're mostly watching the race play out with no interaction. There is also not much to customize at the garage. One suggestion is maybe start with loads of money but only 1 basic car without any equipment first. Then let us choose which part to buy and install.
I think you did a decent job on the customization in the garage UI clarity. Everything is quite understandable on the get-go. One improvement point is you should show your available money in the garage screen. Player starts with $1000 but it is not communicated in the garage screen where you're actually buying for mods.
It seems a bug where there is no UI pop-up after you finish the second race. You are just stuck with the game looping until you reload/refresh the browser page.
That's it for now, keep on working!
