You may have already fixed some of these but:

The word "down" briefly appears during the text scroll for one of the leaflets (pictured below), then vanishes, presumably due to word wrap (I guess it's on the 4th line...

The "Main Menu" button on the "thank you for playing" screen doesn't work.

Clicking on the TV again after playing the duel gives you the "find the remote" quest/dialogue again, overriding the "find the leaflet" one.

Finding the Sapphica leaflet does not update your quest display. (Pictured below)

I managed to interact with the TV twice at once. Results below.

...Actually you can interact with it (and probably other objects) even while the text box is still up... (results below)

...with interesting results. Game seems fun, though, looking forward to playing it when it's been expanded on a little.

Hi again! So. With V0.2 out I found a bunch of bugs, though I suspect some of them aren't new.

Bugs:

(above) The name tags of the guards are obscured by the guards themselves.

(above, below) Sapphica gives its members powers of levitation? (This bug and the last one might be connected, if their idle pose was changed; they both also apply to the other guards and Tulia)

Idly and humorously noting that the searingly bright magenta of the above outfit reminds me of the Garry's Mod missing texture placeholder (below), which briefly made me suspect a missing or placeholder texture.

(above, below) Typo; quatermaster should be quartermaster.

(above) Helping Hand's image is plain white.

This is a stylistic criticism, not a bug, but the text on Extra Slippery Lube ("1" above) is really small and somewhat hard to read. So is the card name on banana-flavored lube, in duels. Maybe this is less of a problem in the downloadable version with higher resolutions? And also when you right click on it. Still, it might be worth considering putting the flavor text in the (future) card collection screen somewhere, rather than on the cards themselves. And no, I did not add that "New Text" (indicated at "2" above) myself. I just have very sharp eyesight.

(above; can't actually show this bug with a still image, it would need to be a GIF) There is an area (indicated with a red outline in the above picture) at the bottom edge of your hand, where if you hover the mouse here, your cards jump rapidly (once per frame) up and down, most likely  because when they're down, the cursor is over them so they go up, but when they're up, the cursor isn't over them any more so they go down.
There is a similar spot on the left side of what I'm going to call the mana circle in the top left corner of each card. (I suspect the best way to fix this is to have a fixed set of selection regions rather than using the pixel-accurate current locations of the cards?)

(above) Right click mostly solves this issue but it would be easier to read the cards in my hand if they appeared on top of the other cards when I hovered over them, not just when I click and drag them around. I am however guessing this isn't as easy as it sounds.

(above)The opponent very often appears to have 99 Invest. This is not actually the case.

The game gets all kinds of buggy (camera stuck in a weird position, quest log still says Enter Sapphica, orgasma not reset) if you go back to the menu and restart the demo from level 2 after completing it, and I ended up having to refresh the page to try out the other deck.

(above) If you've already picked up and are holding a card (by clicking and dragging) when you draw a card for the start of your turn, you can end up with two cards occupying the same place in your hand... fixes itself when you play a card. (Could be fixed by preventing you from picking up cards until after this is done)

I've not been able to reproduce this bug myself in more recent attempts, but I seemed to in one instance be able to skip an opponent's turn by ending my turn twice in a row before she could take hers -- observe the "mana" amounts in this picture: (large picture demonstration) and recall that there are no mana boosting cards in the starter decks. This might have happened because the opponent's deck was stacked with expensive cards and she had nothing to do? Or there might be a more complex explanation? I'm really not sure...

Mordor speak remains for some NPCs/objects (proving grounds and some nearby guards; see linked images)

My favorite bug so far: You can play the same card (as in, not multiple copies, the SAME card) multiple times by quickly clicking on it, dragging a short distance, then releasing the mouse on it while it's floating in the middle of the screen after being played normally. (You do need to have enough mana for each time you copy the effect). I don't have a screenshot of this one and honestly it probably wouldn't help much.

Random final typo: "you're deck is ready" when entering the proving grounds should be "your deck is ready". (you're is "you are")
