At the time of this review, the game is a rather simple demo consisting of one level and a boss fight. The difficulty of the game is quite high, and the demo itself can be rather technical. You have four attacks at your disposal: a punch which does meager damage, a head bounce that deals about twice as much damage as a punch, and two orb variants of increasing power and rarity.
The level itself isn't too difficult save from some slightly wonky collision detection on enemies (on this note, I recommend not using the head-bounce too often), but the real meat of the challenge is the boss, one of the game's titular Titans. Bullets will be flying at you from every which way, and you have to do your best to dodge them as best you can while stripping the Titan down to nothing... or you could employ a bit of strategy and hide in a small alcove to the left side of the screen where bullets can't hit you.
For a platformer, it does well enough... as a self-proclaimed bullet hell, it can be a bit overwhelming since, unlike traditional bullet hell games like the Touhou series and Ikaruga, your eyes need to be all over the screen to play effectively. It's daunting for sure, but it's far from impossible once you're aware of your goal.
