hey!! Thanks for playing!! Waves, these act as a way to clear enemies/buildings threatening to attack you. Think of it as a way to plan your slams so you also clear out any oncoming projectiles from spawning. When you grow, you get a large tide that can be shifted to either direction and clear enemies. Looking back, we do see where this was lost for players, so we intend to release a patch just to make the game clearer and more enjoyable.
