I generally enjoy games by Andrew Schultz, and this was no exception.
It's a small game on a 5x5 chess square with a few short chess puzzles. Using knight moves, you must move around the board to achieve your goals.
+Polish: The game was very smooth. I kept trying to type SUMMON instead of CALL but that's entirely on me.
+Descriptive: I actually like the writing in this more than almost all other Schultz games. It goes in a different direction and I like it.
+Interactivity: The puzzles appealed to me.
+Emotional impact: Genuine enjoyment counts as an emotion, right?
+Would I play it again? Yes, I found it satisfying.
I don't everyone would like this all the time, but I think some people would like this some of the time. If you'd like a brief logic-based brainteaser that wraps itself up nicely, try it out.
