Wow!
Super cool! Very original idea - I have never played something like this before and I liked it a lot.
It would be amazing if the streets would give you a slight speed buff in general.
But again - Wow. There is no need for a map since you will always find the monster again by following the slime balls. It has a level of strategy to it, like you technically want to keep the close pumpkins for bad times and also consider when to pick up the sweets for speed boosting. And all of that with just movement. An indicator, maybe a texture around the monster could help show the "throwing radius".
Good job you guys! Keep it up :)
