The game is very nice and feels very juicy. I will need to come back to the game to play with a friend. However, I just found after replaying, as I wanted to shoot in a different pattern similar to in the video, that the shooter can hit his own colored flowers to level up his shooting pattern.
Maybe instead of shooting right at the enemy in the starting scene, you could place a flower in between both players (not reachable to be captured by the other in time). This way you could be more forgiving to players just jumping in the game and when you just have a level 0 slower shooting pattern just for the start, you wouldn't even affect any balancing issues.
