Thank you so much for your kind words! As you get larger, revealing the map was a pivotal design decision early on. However, we realized some frustration that might come with it and tried to soften it by easier retry buttons and skipping levels for any that don't resonate with the player.
For the block pushing, yes, the first order of business when expanding this is to further sharpen the materialization of the block pushing mechanic. Thank you so much for trying and providing great feedback! Cheers!
