Did you use any free assets? If not, this is an amazing entry!
Loved the music, the slight crumbly sfx as he runs (like the metal is crunching against gravel). The art is great too!
I think that if the lag between input and jump/slash could make it more playable for longer runs (slash right after jump isn't really possible at the moment).
Genuinely liked it as a runner, thanks for making this!
