Oh god... not another robot samurai fighting against falling bombs using rewind, so uninspired ;)
Its a cool little game but it definitely seemed like there were problems as the instructions say 'It maintains the relative position (and physic process) with respect to the previous quadrant' but I was definitely losing my relative position on more than one occasion which made the game more difficult.
The pixel art is clean and simple, the overall mechanics are good and well thought out and music is pretty typical of this style of game. Its just the execution (relative position) that needs a little work.
