The game is very challenging, before I bought it I heard it was challenging but i wasn't fully aware of how hard it was, the soundtrack is great, art style is great, the game is great, reccomended 9/10. It's mainly defeating bosses, when you do beat a boss it feels like a accomplishment. since the game is hard it'll last you a while in terms of gameplay because you will keep trying again and again, there's a shop where can buy things like charm and different attacks for coin which are found in run and gun levels, overall i love the game and i'm still trying to get through it.
