I do not like:
- no gameplay, only slaughter. Make some missions and other actions than fighting, or more fighting moves.
- You can only move to 8 sides. I do like it more when you can move free.
- If you attack you can't walk. When I'm following a person I want to kill and I click the attack button I stop while the 'enemy' is walking further. This way it is way too hard to stab someone in the back. Atacking and walking have to be done at the same time.

i do like:
- the cartoonish look
- the characters
- the music + sounds
- the level design

...so actually I like the design of the game, but I don't like to play it.
