I really appreciate you not only playing but leaving such great feedback. I'm glad you were able to have some fun with it.
I've reflected on the game on and off since I've released it and mostly agree with what you've said. While searching for a balance between it being challenging and having those "aha" moments for the player, I ultimately veered into it being far more difficult than I realized and probably a bit too convoluted in a way. I do think there's something to the base concept and mechanics and plan on maybe revisiting them in a different way in the future, but this was for sure a learning experience for me.
Thanks again!
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.
