It's a game that has been multiple times.
The unique spin you put into it, like the demon and angel "balloons", is alright. But it doesn't do much from making me feel like I've played the same game before.
The chains are annoying too. Since this is a similar game to other titles, I don't have the patience to deal with that.
The physics also seem a bit simplified compared to other games of the same nature. The hitboxes are large and the projectiles large. Though given how it is necessary to quickly hit things, I guess it works out.
