FWIW I do want to say that I think it is still a decent puzzler, just one that some will want to check out of at some point due to said difficulty spikes. I managed to finish the rest of the full 40 today and I would say that the difficulty level in the final ten or so stages was more manageable, having to trigger a block disappearing as opposed to it alternating each turn may simply be easier to grasp. Anyways was glad to give it a shot, not sure I saw a game use that kind of "count down & disappear" mechanic in this context before so credit for showing me something new, best of luck with whatever you get to next.
