I was referring not to the name “DelveTris” but to the tagline “Tetris your way…”. And the song from freesound, ignoring TTC’s trademark, is licensed under CC-BY 4.0. Which means your game or its description must contain a specific bit of text stating who made this rendition of the song and where it came from.
As for the dirt: my playthrough had no dirt at the bottom, just a smattering of what looked like bloody knives
Oh whoops, fixed up those bits in the text.
If you were getting rows with knives at the bottom then you reached a monster. I wanted to do some hit/attack sounds and effects so that it'd be more obvious when a monster's attacking but only had time to do a little flash on the side when the monster appears. There's some amount of variance in how disruptive the enemies I made are, I do like where I had the monster that sticks knives in your pile at, just think I could have sold it a bit more if I had time to do some effects for all the enemies, there's only maybe two where their presence is very overtly obvious without any extra visual effects
