Hello, glad you like it :) . Thank you for the feedback , those are some good idea will look into. I tried to give a grace period when panel changes color so even if a bubble color which is previous panel color is touches the top u wont lose point. Think the period needs to tweak more or be given a better visual cue. Breaking the game into parts sounds great. Moving forward will introduce one mechanic at a time so as to let the player ease in how to play the game . Cheers.
