Common Bullet hell games:
Dodge the bullet to survive, just don't get hit and keep shooting to kill.
Slice, roll and ram your enemies till they die. Cant avoid getting hit? Spam your abilities :D
Overall this game is amazing to me.
The I like the unique game-play of this where you have multiple abilities to survive. Unlike most other bullet hell games where your only option of survival is to dodge the bullets.
The music itself is very suiting and nice too. The art itself is also great.
The only downside of this game is the boss-fights mainly.
The bosses' attack are too repetitive, they always do the same pattern over and over again until they reach low health (which is, by the time that happens, you can easily spam a few abilities and the boss dies immediately).
Plus with that repetitiveness, they also have a ton of health, which may make the boss-fight itself boring overall.
Otherwise, this game is extremely awesome.
