Rhythm Pulse

Overview

Rhythm Pulse is a four-lane falling-note rhythm game in the tradition of console music games. Colored notes slide down a neon highway toward a bright hit line, and your job is to strike the matching lane the instant each note crosses it. Land within 50 milliseconds and you score a Perfect worth 300 points; within 110 milliseconds earns a Good worth 120. Anything that slides more than 150 milliseconds past the line is a Miss, which breaks your combo and drains the pulse gauge at the top of the screen. If that gauge reaches zero, the song ends early and you fail it. Every song is generated in the browser: a synthesized kick, hi-hat and bassline keep the beat while each note you hit plays a lead tone from the song's own scale, so a clean run literally plays the melody. Six original songs climb from a relaxed 96 BPM eighth-note groove to a 156 BPM sixteenth-note sprint with frequent two-note chords.

How to Play

Choose a song from the list on the title screen with the mouse, a tap, or the Up and Down arrows, then press Play Song (or Space). Play the lanes with D, F, J and K, or with the arrow keys Left, Down, Up and Right. On a phone or tablet, tap anywhere inside a lane; multi-touch is supported, so two thumbs can take chords together. The thin bar under the gauge shows how much of the song is left, and faint horizontal lines mark every beat, with thicker lines on each bar. P pauses and resumes, and R restarts the current song. When a song ends you see your grade, accuracy, hit counts and best combo, with buttons to retry, move on to the next song, or return to the list.

Tips & Strategy

Read the beat lines, not the notes alone: notes always sit on an eighth or sixteenth subdivision, so counting the bar lines tells you when a dense run is coming. The multiplier is where scores are made. It jumps to x2 at 10 hits, x3 at 25 and x4 at 50, so a single miss late in a song can cost more than ten early ones; on hard songs, play the opening bars safely and protect the streak. Because ghost taps are free, keep idle fingers bouncing in time instead of hovering, which keeps your rhythm steady through gaps. Chords on the later songs are almost always two lanes apart, such as lanes one and three, so place index and ring fingers ready for that shape. Every eighth bar is a lighter breather; use it to reset your hand position. If the gauge turns red, prioritise Goods over chasing Perfects, since each Perfect only refills two points and each miss on Overdrive Sun costs twelve.

What Makes It Distinct

Most browser rhythm games stream an audio file and ask you to keep up. Rhythm Pulse builds the music from oscillators while you play, and the lead line exists only when you hit notes, so your accuracy is audible as well as scored. The charts are fixed for every player, which makes grades on the harder songs a fair thing to compare.
