Immediately on starting the game, I fell in love with the music. Really well executed concept, the paste preview was an especially nice touch.
Once I got to the lava, I got pretty confused, since when I tried to move down nothing seemed to happen aside from a sound playing. I eventually realized that the lava was spreading into the tile I was trying to move into, killing me. Something to make that a little more clear could be a nice extra touch.
Definitely feels like something that could be expanded into an even larger game (and this one is already impressively large!)
