Very difficult and stressful, but in a fun way: well done! I think the difficulty ramps up a bit fast, and it did get a little annoying when I was just stuck without a card to use at all. Maybe a mechanic to reroll your cards every now and then might help a little bit?

Really dope concept! Kinda stressful, especially when you can't get the right card you need and everyone is honking at you!

Very cool interpretation of the theme! I like the art style and the idea of a card system to control the traffic. Took a while to get used to the cards and maybe colour coding the directions (top, bottom) could have made it easier to at a glance see which is which but it felt really good. 

Only annoyance was the cars beeping every 5 seconds haha but very solid entry !

Really cool entry ! I enjoyed the card system quite a lot !
The minimalist style fit very well with this genre.
The music is nice, though a bit repetitive after a while (and the honking sounds can be a bit annoying in the long run)

Not sure if you went with a fully random generation for the cards, there's been a few occasion where I was completely missing a direction and weren't able to play anything without screwing myself. might be a good improvement for after the jam to condition your card generation to always give at least a direction that you're missing the most so you don't get stuck.

Appart from that, it's a really solid & fun entry, especially fo a first jam !
Good job ! :)
