I really liked my play through. Though I realized at some point that I wouldn't be able to build up the walls in time, I was still compelled to try! The gameplay is intuitive enough that it doesn't require the player to be able to read to figure out the systems in play. I liked the simplicity of the 5x5 tileset, though I could also see this being expanded to other shapes and sizes alongside new features. The art was simple, colourful and conveyed what it needed to. The music was also a great choice. It was very nice.
My only wish would be that there be at least one more dynamic that the player can engage with while the worker's countdown is active, since sometimes it felt like I was just watching the worker clock. That being said, I do think the countdowns add a sense of urgency and make you hope that they finish in time.
Very nice game.
