in Kill Will, we have exactly what we expect to have : a fast game, with a lot of ennemies, in ultra-colorful old*school graphics, where 3D and pixels are mixed together. As soon as the barrier of the Strange is crossed and accepted, this game becomes a way to let off steam where the player runs dans jumps everywhere, killing as many ennemies as possible.
The art in the game is very tasteful, but as a puzzle game its just not good. There are only 2 piece shapes (not counting corners and edges), they aren't rotated, and the game gives you a million ways to make the puzzles even easier than they already are. Hopefully if the developer makes more of these games, they will be more complex.
