This game looks great- visuals read well, and there's a lot of subtle attention to detail!
I'm not as sold on the gameplay. Controls feel very sluggish and unresponsive; while this may be somewhat intentional to make the input "weighty", I didn't enjoy it very much. It seems like I lose when I fail to stack a block on a previous one, but there isn't much feedback to failure- it seems like the block slips, and then a few moments after, when I expect the next piece to fall, the game suddenly ends. Maybe there's an audio cue I'm missing with the web version?
