Andromeda Survivors

Enemies will periodically drop blue pods when destroyed, and you then need to destroy those pods to get either a heart (which heals you significantly) or an XP cluster). I'm pretty sure this needs to be done in a single run and is not cumulative across runs, but it'll happen without trying as you survive for five and then ten minutes.You can get Luck upgrades when leveling up to increase the frequency of enemy drops.
