hi! I liked the music and it is fun to play :)
However, I had hard time identifying the pickup points, maybe making the target houses stand out more would be nice. I think the minimap was a good idea to add but it was lacking the clearly visible pickup points and final destination mark so for me in this state didn't add much. Did you try during the iterations how would the game work with a more zoomed out view? Maybe a sort of a topdown/tps inbetween could make this more easy to find targets etc?
Non the less, this is a fine piece of game, it has a story, visually good (it even has particle effects) and as I sad the music is cool :)
