I like the atmosphere here. Once I figured out how to use the arrow keys correctly in the isometric view it was then a question of depth perception and figuring out where I'd land. The shadow definitely helps when you try to line that up, but the buildings are still a little hard to discern where they are in relation to each other sometimes.
The game definitely creates that frantic atmosphere where I'm struggling between the decision to try and just jump higher versus getting more powerups to slow the encroaching camera. Great job!
