Great concept, great simple style, great music. And extra kudos for having an audio toggle! I also like how the last upgrade tells you that the game is over. Clever!
Unfortunately, the game starts dragging towards the end when it starts looking like the simplest combos, like all blue and one ping, are more effective than anything “smart”. Having multiple rings is great for experimentation, but a bit demoralizing when you keep building some smart system and it still performs worse than the really simple, boring ring next door.
But that was only towards the end. Most of my play-through was highly engaging. Thanks for making this :)
