It's pretty fun little game that is a little rough around the edges. Visuals are adorable, and reminds me very much of Mister Driller, though that makes the lackluster audio stand out that much more.
Echo Blues Effect doesn't loop very well at all, and will cut out if you score above 1000 points. I'm not sure if it's just broken on my end, but the complete lack of sound effects is kind of surprising. An audio clue when the dog is lunging would make it a little easier to play even.
All in all, while a fun and cute game, it really underscores how important audio is to game design.
