I enjoyed this way more than I thought I would.
The random Levels give the game pretty good replayability. And I also like that the upgrades apply to the world instead of the player.
The controls are actually pretty good once you get used to them.
If I had to fix something from the game it would probably be the "move busstop" system to make it cancleable and more intuitive. And I would reset the countdown of an item when you initially pick it up (since a bad map layout can make getting to the first and second position in time sometimes impossible).
What an awesome little concept. I have never seen an game in this direction before
