I'm glad you liked my video. I searched for Halloween games by writing various Halloween-related words in the search bar and playing the games that showed up. That's why Doomslinger Dungeon flew under the radar. I could try it in the future, though.
I'm sorry, but I forgot to use the gacha machines. Although, your game's section of the video was already pretty long, so, even if I did remember to try them, I would've probably skipped them in the review.
