Nice and simple, but the timing is what makes it hard! Never seen an overlap of enemies, so that's good. They just get really close to each other, so I gotta pay attention!
First try got 1400, second try 900. Gonna see what I can get!
Fourth try got 2700 from the sorta exploit of how loss distance is shorter than the attack distance, so just flipping directions rapidly is an easy way to stay alive for a while.
