This game is more clever than the review score makes it out to be. It requires a different sort of thinking than your usual tower climber. The swapping I found is mainly a final resort and I think you made many people confused in that regard. However, those with the patience to keep on playing will find an extremely interesting learning curve that's more about planning than reflexes.
The main problem is that this game is extremely unforgiving. I don't know if I can really blame clunky controls since the gameplay sort of leans on that, but the way you can't touch a block by a single pixel simply makes this too brutal of an experience. Finally, shoutout to the Options Menu. It's actually rather fun messing with the patterns. Could be something you might want to implement in future games :)
