Not too shabby, but I feel like it's a bit bare-bones and way too simple at the moment in many aspects. I think the core is pretty decent: running to the right, strategically jumping/double-jumping to grab burgers to keep your stamina up while trying to get a high score is pretty fun. The music is great, and the game even has some nice touches like a bit of shake when you land.
However, I feel like the gameplay and progression is very minimal: once you've played it for a few seconds you've seen everything. The platforms are incredibly bland: I would much prefer the platforms to be something more colorful like floating islands with grass that have actual edges to them instead of just bland tiled brick squares. Would be nice if the platforms changed as you progress as well: maybe they get smaller or maybe some icey platforms or spike platforms get thrown in the mix for variety. Would be nice if there were more power-ups to spice things up or obstacles to contend with: maybe you have to throw your shuriken or slice through enemies while you're running. Furthermore, while the title screen is presented well with the text dropping in, all of the other events like speed up and game over are presented very blandly with no fanfare: it'd be a lot cooler if speed up was put front and center and had some confetti go off to celebrate you making it farther.
Basically, I think this game needs a lot more to it since Azumi deserves it.
