Let's start of with saying with this game is difficult.
The story and storyboards (both begining and end) are hilarious.
The game has plenty of elements all of which interract with one another. Sometimes however you lose control with each element you would like to interct - Kappa and well are in your area of interaction, you want to slap kappa but you can't because you still possesing that stupid well. I find it really funny that because of this creator always needs to place more than one tombstone. Btw I find Kappa to be useless(aside form killing kitsune).
The arcade graphic doesn't really work for me. Whenever I see something like this I consider it to be playing cheap on nostalgia.
Level design could use some work. I finished levels different way than creator intended by forceful sneaking instead of using smarts. Collision are sometimes broken I would fall from roof to my death instead of climbing.
Music is ok.
Overall: Somewhere between 3 and 3.5
