This is a very weird glitch that I've discovered
Apparently you can press escape to exit a level immediately, even if you're dying, and if you exit a level while dying then quickly visit another chapter's level selection screen before you respawn, the game will respawn you fine, but then when you leave, all of the chapter level selection screens look like the chapter level selection screen that's relevant to the level you left mid-way through a death sequence but it works fine (so for example if I did this glitch with Basic Training, then all the chapter level selection screens would look like Basic Training but you would be able to load all of the levels).
This means that I can access Agility 11-15 and Focus 11-15 which don't normally exist and therefore very buggy. All these levels seem to be a copy of the final level but the colours of all the doors rapidly change and there's no collision on any walls at all (and for Agility, there are some red lines with arrows as demonstrated in my screenshot, I assume these refrence the fish in the level)
Also, when you die three times, you get the usual helpful message pop up, but it says "Text Missing"
my third completed run is a 5:22, is that a good time for a beginner
edit: just got a 5:20 while recording :D
The mods have come to a decision, and it is that all modes should be removed with effect immediately. This is due to too much variation in the game and potential updates meaning we'd have to wipe the boards often.
This does not mean that All Modes will be gone forever, as there is a chance that it may come back if updates come less frequently, and there may be a chance of an alternate version of this coming in the future.
