This one deserves way more love. Fun and unique concept with a ton of levels that approach the game from just about every possible direction. Nice graphics for the time too. I'd go so far as to say that this is the best NES game from before Super Mario Bros.
Yeah, this is an impressively well fleshed-out puzzle platformer. A lot of the later levels do get to be pretty tedious, even after you've figured out the level's schtick, and a couple in particular seemed to barely have any rhyme or reason to their solutions, even in hindsight. Still though, the majority of these puzzles are really well-crafted and the game does a good job putting you in positions that force you to learn all the subtleties to its systems.
OH, YEAH
