If you're bored, then try playing some of these! They're cute and fun to play. Though I can't help ⑨...
Butterfly Flies for Fryhttp://www.ug.it.usyd.edu.au/~lcha6311/Web/bfff.swfThis is where you control Yuyuko on her daily quest to eat Mystia. Click on her to make her jump, avoid danmaku and eat food and Mystia to keep your stamina up. Don't make Yuyuko fall!
Moving towards the left side makes Yuyuko fly faster and moving to the right makes her go slower.
Cirno Traininghttp://www.ug.it.usyd.edu.au/~lcha6311/Web/cirno_training.swfIt's all addition problems, but with a twist. For all numbers that equal 9, you select ⑨, otherwise, you'll have to select the
wrong answer to proceed. (
Thanks to shinji for working it out)
Red Magichttp://www.ug.it.usyd.edu.au/~lcha6311/Web/redmagic.swfThis game is where you have to click on white squares to make it's adjacent squares red. Once you have 4 or more red squares joined, you can click on the red area to clear it and score points. The number of square's you need to join before you can clear it increases as you progress.
Sculpturehttp://www.ug.it.usyd.edu.au/~lcha6311/Web/sculpture.swfThis game stars Sakuya and China, you can pretty much guess what you need to do. To those who are new at Touhou, just click on things to throw knives at

It's pretty amazing what DillusionalTorment and I can do when we're absolutely bored. Here's some updates:
Hold down Z to initiate "Time Stop" which will allow you to remove any unnecessary bullets and 'trash'. The circle around your cross-hair is your hitbox, so just move the cursor out of the way to dodge bullets.
So Nano Ka~http://www.ug.it.usyd.edu.au/~lcha6311/Web/so_nano_ka.swfThis is a game that I can't seem to stop playing. It's where you follow the pattern that Rumia sings.
A is for Automode, just to listen. S is to start game. Z is [So]/high note, X is [Nano]/Middle note and C is [Ka]/low note. The symbol (for non musical people) that looks like a weird 3 is a rest note, where you don't press anything.
(Note: You lose when you make 20 errors. I stopped Score: 1802 when the lag of my computer killed me
) and also, try clicking Rumia's Ribbon! Best for me was 504)Dr. Yagokorohttp://www.ug.it.usyd.edu.au/~lcha6311/Web/dr_yagokoro.swfA game similar to Dr. Mario. The thing is I dunno how to play this game properly. From what I got of it, you have to match up the colours of the pills and set the evil Guya microbes underneath it to clear it.
Marippyhttp://www.ug.it.usyd.edu.au/~lcha6311/Web/marippy.swfWalk around as Marisa, collecting all your belongings from Alice and her dolls. The items that glow yellow gives double points. I think I only made it to stage 4...
Fla-Fla-Flanhttp://chibitami.net/works/flash/fla2flan/index.htmlFlandre is balancing on top of a very pointy tower...I dunno why tho...
Anyways, your goal is to stack and eliminate the crystal-like structures on her wings, getting points along the way. Flandre sways according to the unbalanced weights on her wings so make sure she doesn't lean too far.
Note: If you set crystals closer to Flandre, she doesn't move as much as she does if you set it on the wing tips.
