This looks promising. Those NES Puzzlemaker games are all basically the same. Feels like after you've played one, you've played them all. Your screenshots make your game at least appear a bit more unique.
You should look into NES Maker - it's definitely more work, and has a learning curve for sure, but there may be similar projects out there that you can use for reference to make your fully fledged game.
[EDIT] Just had a chance to play it on my NES and this one is pretty good! While it still felt like a typical NES Puzzlemaker game, there was something about it that made it feel better than most of the others.
