I quite like the gameplay and artstyle, cool effects when they explode. the parallax effects are also nice, visually it is quite pleasing.
I would have loved to have some sort of action/mechanik/skill i could use, maybe turbo, maybe drop some spikes, idk, to have more influence and more things to do. I like that there is friendly fire of the enemys.
As some people said, could be expanded, maybe roguelight with some upgrades etc, ever more increasing difficult, few bosses, upgrades and stuff like that. Maybe have different stats and vehicles which differentiate for the player to choose from.
I think the music and sound is OK, but this is an area where you could improve, a more action packed pumping driving soundtrack, currently it is too chill for my taste for this deathrace ;)
Cool jam entry! well done!
