Kinda easy for a Touhou player. Two of the bosses can be beaten by standing still (one by standing directly in front of it while shots litter the rest of the area). Honestly, the hardest thing about it was using bombs by accident. Master Spark (4 adrenalin) lasts way too long and does too little damage to bosses. Still, it was good for a 20-30 minute distraction. 215827551, 4/5.
