A little strategy I found, I haven't seen anyone else do it (or maybe everyone has already done this and I just haven't seen it and I wasted my time doing this) so I thought I should share this useful info.
Basically if you stand in the middle (where the orbs spawn) and release as they spawn it practically cheeses the waves and makes them really easy.
You even get some nice score and a release for doing so.
You can do this in stage 6 too as there is a similar wave in that stage but of course it only works with Summer releases.
