1. Suppression "Super ego" - 4th card, similar to the 3rd but this time the hearts spiral upwards coming from the bottom. Is there any pattern or area where it's easier to dodge, becase I can't read their movement at all.
Stay near the bottom, because the gaps are bigger there. Alternate dodging left and right - watch one side for an opening, then unfocus and move through the gap, and immediately start watching the opposite side for the next gap.
2. Depths 'Genetic of the subconcious' - I faced this card once, and I died pretty much at the first wave. Then I actually was surprised at how easy it was to dodge them, my problem however was that I found it hard to stay underneath Koishi and beat her before the time limit, tips? (is her movement a fixed pattern/random/aimed?)
Her movement is a combination of a fixed pattern and aimed. When you hear the "charge-up" sound, the next movement is aimed. The rest are fixed points, if I'm not mistaken.
4. Subterranean rose - Never reached it, any advice beforehand?
Make sure you're actually clear of the roses after you pass through the bullets - they extend quite a bit upwards, so make sure you don't get hit by a rose appearing below you. For the last phase, there are two ways to handle it: Either remember the next color, or just make sure to move up an odd number of bullets each time. If you move up 3 at a time, you'll still be sliding downwards gradually, so you need to move up 5 at once every so often.
