You drag percussion onto a 32x32 pixel field and route traveling pulses through it so that the order of strikes reproduces a target rhythm. Built by cxong for LOWREZ jam 2014 and rendered with Phaser CE in the jam's signature low-resolution aesthetic, the game hands you thirteen drum types — bass, snare, hi-hats, cowbell, bongos, claves, guiro, rimshot, tambourine, metal-beat, and more — alongside bouncy and redirector drums that fold a pulse back across the grid to change which instrument it hits next. The result reads closer to a logic puzzle wearing a music skin than a reflex rhythm game: you decode a target pattern, then engineer a layout whose pulse path plays it back. Tempo climbs steadily as the staged screens carry you from Easy through Tricky toward the credits, and the project ships MIT-licensed and open source, which makes it as friendly to tinkerers as to players who just want to solve percussion puzzles on a tiny canvas.",[47,56,58],{"id":57},"how-to-play","How to Play",[52,60,61],{},"The objective on every screen is to recreate the target percussion rhythm shown in the solution strip at the bottom of the playfield. Drag a drum from the palette onto the 32x32 grid, then position beat-generator, bouncy, and redirector drums so their emitted pulses thread through your instruments in the correct order. Click the solution strip at any time to audition the target rhythm and compare it against what your layout plays back. There are no keyboard controls — everything runs through mouse drag-and-drop — and touch is not explicitly supported, so a single-pointer mouse is the intended input. Click to advance once a level is solved, and the tempo climbs with each staged screen as the BPM rises from 67 toward 188 through the Easy and Tricky sets.",[47,63,65],{"id":64},"tips-strategy","Tips & Strategy",[52,67,68],{},"Read the target rhythm in the solution strip before placing a single drum: the order of strikes dictates the path your pulse must take, so mapping hits to instruments first turns the screen into a routing problem rather than a guessing game. Lean on redirector and bouncy drums to fold a pulse back across the grid, which lets one beat-generator strike several instruments in sequence instead of demanding an emitter for every hit. Keep pulse paths short where you can, because a longer route delays the strike and can shove a note off the beat as the BPM climbs toward 188. Audition often on the Tricky screens — clicking the solution strip to compare your layout's playback against the target is faster than tracing pulse paths by eye once the grid fills. Lay down the bass and snare first and build the supporting instruments around them, since the backbone of the rhythm has to land before the ornaments matter.",{"title":70,"searchDepth":71,"depth":71,"links":72},"",2,[73,74,75],{"id":49,"depth":71,"text":50},{"id":57,"depth":71,"text":58},{"id":64,"depth":71,"text":65},"md",null,{},true,"\u002Fgames\u002Fbeatrix",{"description":6},"games\u002Fbeatrix","eG9OfLjJV0gGcpyL8VhszAboD0j937O5gGElJu_EDxI",1783575111631]
