Hi! So I already left a small opinion under Your game:) I hope it's helpful though I will play more due to the progression tomorrow when I have time (though I wanna make a game for Kenney Jam so not sure).
The UI, main menus and all are generally yet to change, but still this was not a priority, but I will try to definetely make it feel like something is happening in there, thanks for pointing out how static and boring it feels haha
About the wall - it's still an ongoing fight in my head. Really the only time it stops You is when You hit the wall from the front at certain angles (straight from the front will bump You back, while a bigger angle like hitting it with a back of the car while drifting will really just slow You down a bit). You can take a deeper look at it if You want, but honestly I feel like it feels a bit more fair compared to how it worked before. Especially after adding A LOT of grass.
Sound and music is of course yet to come:)
About more effects and particles might be a good idea. I don't have an idea yet what I can do, but definetely will try to work on some to make the game look more interesting thanks!
