Rhythm Kingdom

Split controls are an old and slightly evil idea. One hand moves you, the other hits the beat, and the arcades used to do that to people on purpose. Keeping it flat and 2D was smart aswell, because a rhythm game is finished the second you can't read the screen. Unlocking actions as you go gives a short loop somewhere to grow into.

Rhythm is the hardest genre to get right. Timing windows and browser audio latency will quietly ruin you, and splitting the controls doubles the amount a player has to learn. Big ask, and no, it isn't fully pulled off here. But manual movement layered over rhythmic actions is a design in its own right rather than a reskin, and someone should push it further.

Split control is where this gets interesting. Move freely, fire on the beat, so your hands end up running two clocks at once. That's a real ask. New actions unlock as you go, so the demand ramps rather than repeats, and that's the correct decision. Rhythm games need tight input ahead of everything else, and this is built small enough to stand a chance at it.
