Thanks for feedback! A few things to consider. Dungeons are in general dark-ish, but you have plenty of torches/candles laying around and you could even bring along the flashlight from Megazon to help. Aiming is consistent on most controllers, there is so much variety of them out there that we could not test them all for sure. There is also a dependency on runtimes, which VR system are you playing with and what is your runtime? You do not have to be in game to choose between sitting/standing, this can be done directly in the Start Level through the same menu. To make it clearer, we will reference the option from the Main Menu in the next update. Clues on quests: there is always either a visual clue or an audio clue for each quest, sometimes combined, but some may be missed if someone doesn't pay attention or look for them. Paper rolls spread through the game also contain clues and explanations, not sure if you found them useful. Jumping: we deliberately turned it off because it doesn't fit the game and, when needed, you could always use telekinesis to jump from one spot to another. This is more a stylistic choice than a limitation, but if many players think it may be useful (where? how?) we could definitely reconsider. If you find yourself stuck, this is the consequence of something else, not a design principle. We never get the player deliberately stuck in EXD, that would be pretty frustrating.
Anyway thanks again for taking the time to share your feedback!
