A Grand Challenge!!
As of this review, I managed to get all the way to Level 19 without consulting the walkthrough. The best strategy I have for the level only puts me one move away from finishing the level (with ALL the stars). Kept thinking to myself of all the attempts I made, if only the Finish was just ONE move closer on that level, I'd have completed it quite some time ago.
Other than that, excellent work, I felt a sense of confidence with how everything was put together from the gameplay to the music (which sounds much like a song I one day planned to release on the Audio Portal, when I finish it), to the achievements and stats that I've acquired in just a bit of time.
Great work, SilenGames. I look forward to seeing more future works from you.
