There are shoot 'em up games, and there are bullet hell games. Then came the danmaku, translated from Japanese as "bullet curtain." If you're up for a challenge, you might want to try this Wiibrew game-in-development, Touhou Fangame, a recreation of Project Shrine Maiden for the Wii. Here's the changelog for Beta 2 of Touhou Fangame:

* Quite a lot!
* Added multiplayer!
* Using WPAD now, so no more 1&2 nonsense.
* Sound Effects.
* Much more hellish patterns.
* Added option saving. You MUST create the directory /saves/Touhou/ and create a blank text file called Touhou.xml in that directory.
* Speed settings.
* Rumble settings.
* God mode setting. (Doesn't save)
* CANCER&AIDS setting. This is actually Wiimote pointer, but because it is so terrible, this is what it is called.
* Couple graphical adjustments.
* Many background things fixed. Performance is much better now.
* After game ends, returns to loader. This must be done because I can't free some resources created during the game, and it will eventually crash after starting the game multiple times. Sorry, hope to get that fixed next release!
* After game over, displays how long it took you to die (or win).
* Shiny menu :P
* New HBC Icon. Thanks LowLines!
