Hm ...
I was a bit dissappointed (?) or maybe surprised - somehow after the gorgeous main menu with the chill ambience, I did not expect a gotta-go-fast next.
But with that out of the way, the game was great. Loved the Play-session time for a level, and as you mentioned i guess you were eager to add some more but deadline cut you off there.
However i think its a great display of what can still come, therefore: well done!
And congratulation on finishing your first game jam.
