I've encountered a few bugs, some minor, some more significant.  I'm not 100% sure of the cause of all of them.

• Fullscreen mode doesn't engage when you start the game despite having it selected in the options.

• You can break your inventory in the clothing equip screen.  If you have at least three pieces of clothing (the two base plus the bunny tail, for instance), you can overwrite one of their entries in the selection boxes on the right.  I think what you have to do is click one on the right (the dress, for example), then click one of the equipment slots holding an item that's not what you chose on the right (the slot with underwear equipped, for example).  If I recall what I did correctly, that will replace the dress with the underwear in the right-hand box.  Note that it doesn't actually duplicate the item, it merely makes the item exist in both boxes.  If you save your game and then load it again, you will have only two boxes again, one holding underwear, one holding the dress.

• I've run into a crash a few times related to having sex with two tentacles at the same time.  I think it might be the result of a tentacle you've already had sex with having sex with you again, which normally doesn't happen?

• Are the purple portals supposed to be functional fast travel points?  If so, none of them work.  The portal inside the hub doesn't function at all, and the portals elsewhere just teleport you inside the nearby boss arena.

• I ran into one instance where the healer wouldn't recognize that the main character was gaping until I saved and reloaded.  Erisia would just keep asking for regular healing.  I haven't reproduced it at all though, so I'm not sure what caused it.

Edit:  I was so focused on try to remember the bugs and how they triggered, I forgot to say that despite the problems I'm enjoying the game.  It's refreshing to find a game on here that's not visual novel #8725 and actually has good, well thought out mechanics.

I'm running into an issue with the quest Au Naturel. I get stripped by enemies and my status shows up as "undressed". When I go to the nurse to get healed, the clothes reappear, but there is no increment on the Au Naturel quest.  This has always occurred with this quest. I'm assuming the issue is I need to have the "stripped" condition, but I can't figure out why sometimes, losing all my clothes and health leads to "stripped", and other times, it shows up as just "undressed".

I get a movement bug related to wall jumping. It's pretty inconsistent but I feel like I recreate it enough that it's a problem.

Problem: When wall jumping from a side and holding that key while jumping off the wall, my horizontal movement completely locks up and the only way to get out of it is to jump/drop down.

Testing: I used the entrance to the maze with the two wood walkways as a testing area. Going from the bottom, wall jumping on the left side to the top wood walkway holding the A key the whole time. The movement lock seems to trigger when I perfectly land on the walkway before I would turn the other way from holding the A key. I don't know if it's some weird velocity issue where it's cancelling itself out or maybe even an area trigger issue, but I doubt that.
