I have played the PC version and liked it to a medium-ish degree, but I do not play especially many shooters. I've heard voices among Touhou players that they didn't particularly like it, due to the overbloated game mechanics. The tackle you mentioned is somewhat forced on you as a spellcard-ender. What's wrong with just depleting a boss' health?
I wonder if I should buy a game like this again that I already have. On the one hand I'm not super-stoked for this one, on the other I like to support localization efforts of anything Touhou. I'll probably decide over the next few days. It is pretty expensive with 25 ? unfortunately. Discounted if you have a PSN-subscription but I currently don't.
You don't actually find this game if you search "Touhou" in the store, it must be "Azure" instead. That's an oversight.
