C64U (Starlite) with release firmware (SW 3.14, Ultimate core 121, C64U FPGA 1.47) & ArcadeR joystick.
Game played fine, seemed to lock up when I entered no name for the high score.
Felt like I had some unclearable tiles from the start, don't know if there is another way to clear them besides joining two powered nets together.
It feels like a fun once in a while game. (I'm not generally a fan of falling block games, so this feels more interesting than most to me.)
