Really enjoyed playing this - was definitely challenging. A bug i noticed is that it's possible to just hold space and soar very high over the game area, which doesn't net you points but is still worth mentioning. I also noticed an issue with the jumping where sometimes buildings spawn too close together so you don't have time to land and jump before smacking into one. Great submission though, if you worked on it more you'd probably be able to put this on a mobile storefront.
