this is a really cool idea! took a while to get the hang of it and i still havent been able to beat the 2nd delivery despite doing all the others lol but was still fun
the music was nice but got a little annoying after a while, would have been nice to have some more sound effects
the switching of modes is really cool! but having shift both boost and brake between the modes was a little weird, often was doing the opposite of what i hoped to do because of it. i think it would have been cool if the break could have been used to drift instead of just dead stop, but the dead stop did help my times in a lot of places
the world/level design is quite interesting (in a good way) albeit a little jank at times.
i enjoyed this overall after spending a bit of time getting used to it :)
