This would make a great mobile game with a bit more development I think. It's really got that Subway Surfers / Temple Run feel to it.
My best score was 272, I reckon I might be able to crack 300, but It's probably a case on rolling the RNG a bit in my favour. I don't think i'll be hitting 500 though!
Well done for a great first jam submission, it's a real achievement to make something in 4 days.
