Very fun game, I've been enjoying it a lot! I've always been been disappointed by the music in the 'falling block' port on the NES, and this homebrew really remedies that, with an awesome soundtrack that is awfully catchy. The Kraken mechanic is really fun and adds an extra challenge to an already perfect title (especially on 'fixed' mode). I also love that you can fast drop blocks, quite the modern convenience. And perhaps best of all you can play it on your real NES if you have a flashcart. Highly recommended, I really don't have anything negative to say. Great work!
