Hints
Use Tally mode to train on the specific levels that are causing you trouble.
Watch for the telltale spluttering fireworks of an enemy about to spawn. Hang around, and you'll be killed as the enemy materialises.
Prioritise your shots carefully. Don't crack open the Katamari-ensue enemies until you've cleared the surrounding threats first.
Atlas is an action-rpg with rogue-like elements where you use your ability to control the ground to fight the enemies and move through procedurally generated worlds.
