This is a pretty boring example of the running platformer genre.
Having played, and enjoyed, similar games in the past I hoped to see plenty of upgrades, pickups and achievements to add layers of interest - but nope... None. Nada. Zilch.
On top of that the jumping feels totally unnatural and unintuitive which, for a game where your ONLY movement is through jumping, is pretty crappy IMO.
Music is OK. This game actually reminds me a lot to strike force kitty (but where you now can control the attacks and you are a one ninja fox army), the game in general is pretty easy, is more like a game to kill some time. The most significative issue (as many others have mentioned) is the jumping, sometimes, it just makes you fail at some part of the level more than just helping you, so, woopsie if you used it before it was suposed to, now, you won't be able to jump those spikes!...maybe some more things would make it better, or at least would make people come back and replay it but, at least, no thanks, I pass
