When I first saw this game, I mistook it for a shooting game, in the sense that you run around dodging the enemy while you fire at them from afar (The problems of not reading and looking at the game carefully!)
At first, it kind of felt hard, it wasn't easy getting your bombs to detonate right in front of your enemies' faces when both sides are moving. Your bombs are affected by your surrounding, which are in turn, affected by your bombs, your movements, and the enemies' movements. This surrounding of yours is very important because it will affect everyone's movement. You can drop absorbtion bombs which will compress the surroundings, dragging everything, bombs, enemies (and you!) into it like a black hole. You can even absorb them to yourself, (be careful of letting them touch your head! Your hitbox is in your head) causing them to follow you in a line and crushing each other. Spin around in a circle, and your enemy will ball up and crush each other to death (or be crushed by the surroundings)
It's hard to explain. I found this game fun because there's a slight tactic to it. Simply placing bombs at the enemy's location might not work, and you would have exploit the enemy's patterns and your own abilities to be able to blow it up. You can also do the tactic above, carefully compressing the space in the surrounding and forcing the enemy to be squished by the web or by each other.
Well, I liked this game and would recommend it for anyone who wants to try something new
Oh, and by the way
Good luck on bullet hells. It's a Japanese game, of course your enemies will be firing at you from everywhere
