About
Sort chips, mix alloys, keep a tidy lab — that's the idea behind FlaiSkei, built as two small bench tools.
Sieve Bench: pick a drawer, type a cut-off mass, press Cut. Chips lighter than your number drop left, the rest drop right. Clear every drawer with the right split to pass the chapter. Sixty levels start with one simple cut and slowly add dead keys, twin masses, and linked trays solved as a pair.
Crucible Flick: drag anywhere to aim, let go to flick a bead into a band. Fill every colored band exactly, no more and no fewer, and the mix is done. Eighty levels bring mirrored chutes and heavier beads that need a firmer flick.
Records keeps your pass counts for both benches. Presets queue several cuts before a run, and Setup has plain sliders for tap sensitivity.
Free play covers all sixty Sieve levels, eighty Crucible levels, and one custom bench slot with the basic knobs. One purchase, the Fall Lab Dossier, opens the other five slots plus the twist-tier and card-size knobs — a single one-time unlock, no subscription.
Next: open the Bench tab, pick Sieve or Crucible, and start with level one.
