Great entry! The visuals were really good, and combined with the music it definitely gave me the vibe of old PS1 sports games.
It sometimes felt a little unpredictable which direction the dude would lean; I'd sometimes be mostly balanced and suddenly jerk to the right or left when there wasn't a very strong curve. I think I might just not have the feel down yet.
It would be cool to see this extended with an infinite/procedurally generated mode or with bonuses or powerups you need to lean dangerously far to collect.
Great work for 72 hours!
