Thank you so much for playing ʕ•ᴥ•ʔ ♡ You are right about the game needing some more depth in terms of mechanics to keep it engaging, the mine-sweeper approach is an interesting suggestion and something I will explore in later updates!
Thank you so much for your feedback, the columns do hide things from view, there are some camera controls to rotate but it has issues with movement controls at the moment.
