I think this was a really clever idea with a solid core mechanic and amazing audio and visual designs, but I just couldn't wrap my head around the controls, especially with regards to how the X's work. Sometimes the red blocks stopped me from putting a block down, sometimes it got placed no problem. Sometimes the green X's stopped a loop from playing; other times I couldn't even place a block there. Is it based on the individual block's size? Shape? Colour? Glitchiness? I honestly could not find a rhyme or reason for it, which made it super frustrating when I want to test out a potential solution only for the game to respond "nuh uh."
