The graphics have a distinct cartoonish style that really works for the genre and the story. The palette is minimal but effective, and the animations are well done.
The sound effects design here is simple if not almost non-existent. The music tracks are ripped from other games so the sound design gets a low score in that regard, even though the tracks used are fitting.
This is a fairly short game, with only a handful of puzzles. The puzzles are challenging though, so this game should keep you occupied and give you at least a good two to three hour playtime.
