Please note: This is the second iteration of this review following an update and comment from the developer. However, it is not overly different to the first.
I purchased this game due to the premise - an anime style ninja platformer (if that makes sense). However, it was a little bit underwhelming and disappointing.
Gameplay is pretty much how you would expect your normal platformer - it is nothing special. There are 3 levels in each stage, with the last being a boss battle. Each level gets more difficult as it goes along (as you'd expect). Whilst what you get here is nothing too bad, very few new gimmicks are introduced as you go along (certainly no new enemies (excluding bosses) in the second and third stages), making gameplay seem a little monotonous at times. The secret ninja technique mechanic is ok, but it is a shame that these cannot be used in the boss fights and that there aren't more to unlock or use (I seem to only ever use one).
Controls are unfortunetly clunky and still feel a little slow despite the update. There is no tutorial - and as far as I am aware the keyboard controls are a little odd. Despite using an xbox controller, controls in some areas are a bit tempermental; this is especially the case with the wallhang aspect, whereby getting a bit close to a wall sticks you to it, leaving you to either slide or jump umpteen steps in the opposite direction. These controls ultimately (and unfortunetly) affect gameplay, making it difficult to dodge in some situations and leaving some areas a little bit tedious to navigate.
In other areas, the game is adequate but not excellent. Graphics are standard, with some areas featuring tiling that is a touch too obvious. Sound works but is nothing special. Cutscenes are relatively uneventful and slow, and can be a little slow to skip.
All in all, it is and little things that let this game down - it just needs a bit more usability and polish. Every time you die or which to retry, you have to do so from the level menu; I'd be more inclined to continue playing if there was a restart button on the menu or game over screen. Likewise, there could be more options changing sound volumes in game. Again, bosses could be better - the first two bosses were both disappointingly repetitive affairs, especially as one critic outlined them as "impressive and fun".
Whilst nothing special was necessarily expected from this game, the controls and little usability things prevent it from being a decent game. That is not to say it is a bad game - some people will definitely find some charm within and with the game as cheap as chips it might be worth a look. However, I can't say I got a great deal of enjoyment from it - whilst the premise has potential, the overall controls and execution of the game could be a lot smoother.
