I played it twice (and got fifth both times). It was pretty fun, so I want to play it again and see if I can do better.
There’s music, but it feels a bit repetitive. But it does give a sense of speed when you’re racing. A fun idea to try out could be making the music slow down when you go slower, and maybe have some instruments that only play when you’re going fast. But for a jam game, that music is definitely good enough (and you have different music on the main menu too).
As for the visuals, I really like them. The colours add an interesting atmosphere. And the cars look nice (and so does the level, but when you’re moving fast, you don’t really stop to look at the sprites you zoom by. But the parallax background is pretty. But I feel like the text in the menu, level description and credits screen look a little bit off. Not so much the title of the game (even though it looks like it’s drawn in a lower resolution and scaled with a good pixel art scaling algorithm). But it’s a bit hard to read the letters m and w in the credits screen and track description. The track description would have been easier to read with a one-pixel gap between lines of text. (The H below the y looks like an A because the letters touch). 32-bit consoles could handle proportional fonts, and usually they’d keep text short or not show all of it on screen at once (a track selection screen could have an image of the track and a scrollable description below or next to it. At least the text has a colour (white) that’s easy to read on the background (purple).
And one nitpick about the second line in the game’s title: The horizontal stroke in the A is a bit low and the one in the G is a bit high. I think it would look better if you matched them to the height of the joints in the middle of the B and the R. In a short bit of text like a title it doesn’t really matter that much though. But I thought I’d mention it anyway. (I’m not an expert i this, just a bit of a nerd.)
Of the games from this jam that I could play in browser, I think this is the one I like most.
