Thanks for the feedback and the kind words !
Yea, unfortunately we didn't have the time to put the end screen due to... well 48h is short ^^ But we have it now :p
And the braking feedback is also something we are thinking on, amongst other things ;)
We are pleased to see so many nice comments and we want to improve and polish the game. We will submit new versions after the jam :) I hope you'll play it again :)
