With all Feedback Quest 9 games, I play each game for 30 minutes or so to provide context for my comments.
I really liked the concept of this game, but I found it really difficult to actually play and enjoy. The game asked if you wanted a tutorial, but didn't actually give a tutorial, which likely added to the frustration. For example, I was never quite sure what all the red marks that were growing were supposed to mean, though I presumed it was bad and recognized that holding my eyes closed made it go away.
I liked the multiple views that were color-coded, and that blinking changed the scene, but I couldn't tell if it was supposed to be 2 or 3 versions. Some doors that were open appeared closed while doing the blink thing, unless I was standing near it; then they were properly open again.
Having to drop the battery and then insert it into the gun was a frustration point, and it seems like it should just have a load option when you mouse over. Some of the mouse-over area hitboxes seemed a little off as well. And when I inserted the battery into the shield per the image, it never actually worked or showed, even with the battery fully charged and trying to swap between the two I had. That's where I got stuck and stopped playing.
Some of my viewers found the constant blinking of the shield not having a charge annoying.
