A very cool game and great submission albeit lacking an in-game tutorial.
I will say that the bosses, or rather boss as I cant get past the first, are tuned a tad bit too high in terms of difficulty for my preferences.
Pretty much every attack hits me before I even see it and as the boss is often of screen I cant even see them windup or anything. Slightly slower projectiles and attacks would have helped.
But overall this is a me issue due to lacking the skill combined with poor reflexes.
From what little of the game I could see its really well made and well polished. And I will rate assuming the rest of the game is according to the same quality.
I may come back to this one for another attempt after checking out other games.
