#glitch13

In Ten Desires ver. 0.01a and ver. 1.00a if you had all sounds muted and selected Default from the Option menu, the BGM Vol would jump to 100% but no actual music would play.

You may have heard about the glitch regarding the Manual in Ten Desires from the touhou wiki. It mentions there that if you open the Manual 15 or more times, and then you go and select a difficulty and after that return to the difficulty screen, you will be met with a garbled up text. If you select that text and proceed to start the game, you will be playing the Extra stage on Hard difficulty, except there are no enemies and nothing else happens.

I've tested this myself and I would like to add few more things which are currently not mentioned there. Upon selecting the garbled text, it will turn into "Lunatic Mode", although neither the stage location or the difficulty shown in the upper corner are related to Lunatic. When you launch this bugged stage at first you are capable of shooting and bombing, but as soon as you kill an invisible enemy you will stop being able to do anything else than fly around. You will even lose the ability to focus. Also, the Point Value meter will show 500,000 instead of the regular 20,000 as in a regular Extra stage.

If you do the Manual glitch and choose Extra Start instead of Game Start, when you go back to the difficulty screen before choosing a character, the difficulty will be gone, showing nothing on the screen. However if you proceed to play it, it will just be a regular Extra stage.

Demo Play replays from Ten Desires.

The order in which they appear is always the same: stage 1 Sanae, stage 2 Youmu and stage 3 Marisa (all three on Hard difficulty).

No Demo Play with Reimu is triggered. It is a bit odd that she wouldn't have any, since she is a playable character.

However, if you peek into the game files, it actually exists. A replay of stage 5 with Reimu. I’m not sure what’s preventing it from being played.

In Ten Desires you can see a falling petal effect on the background if you select most of the menu options. But when you return back to the main menu, the petals would be gone.

However, when returning from Spell Practice, you will still be able to see falling petals in the right side of the screen. Entering and exiting any other menu (exepting "Option") will get rid of the petals.

Toyosatomimi no Miko does not have that colourful pattern behind her (aura) during her last spellcard in Ten Desires (regular run or Practice Start). However, it is present in Spell Practice.

In ver. 1.00b of Ten Desires, the timer position was changed in Spell Practice. The timer goes to the top of the screen, making it overlay with the spellcard name if the name is long enough. The position has been corrected in ver. 1.00c.

In regular playthrough, the timer position is the same in all three versions.

While documenting the strange behaviour of the timer in Ten Desires (see /post/716600614441926656/), I couldn't manage to trigger it for Seiga.

Even when slowing down the recording, the timer seemed to start from 55.00 seconds without anything else prior to it.

I've contacted Nylilsa (from nylilsa.github.io) to help me with this. It seems that it can happen for Seiga, but instead of the whole timer, only the milliseconds part is shown (and that only for a small moment). Many thanks to Nylilsa for helping me out with this!

It is very easy to miss it. Without slowing down the recording is nearly impossible to see it with the naked eye at full speed.

Also, while I was trying to trigger this in Reimu's route, there was a .98 shown before the timer, but then the timer showed 54.98 right in the next frame, so I thought it was the .98 from the boss timer and not from the midboss timer. But in another attempt (see gifs from above, I've managed to get .31 and then the timer turned 55.00, confirming that the .31 came from the 32.31 of the midboss).

In Spell Practice of Ten Desires, Seiga Kaku generates her healthbar before the spellcard is fully triggered. If you shoot her right after entering Spell Practice you will be able to deplete a bit from that healthbar (although not completely), but Seiga will go back to full health once the spellcard is triggered.
