Start with a skinny character and turn them into a muscle beast using nothing but household items! KASLA! is a rhythm and timing fitness game: your character does the workout, you decide how clean every rep is.
💪 HOW TO PLAY
Tap the moment the gauge hits the yellow zone to land a "PEAK" rep. Chain peaks to grow your combo, heat up the room and multiply your score. Tap too early or too late and it's "BAD FORM" — combo gone. As the set goes on your character gets tired and the zone gets tighter. Short, fast, addictive.
🏋️ 6 EXERCISES, 6 MUSCLE GROUPS
Bottle Curl (arms), Jug Press (shoulders), Chair Squat (legs), Towel Row (back), Push-up (chest) and Crunch (core). No gym — just a water bottle, a jug, a towel and a chair.
📈 YOUR CHARACTER GROWS
Every exercise levels up one muscle (up to Lv.10), and your character visibly changes: skinny → fit → buff → BEAST. But like real bodybuilding, you have to train balanced — skip a muscle and you won't get buff. No skipping leg day! The progress bar on the menu shows how close the next stage is and what to train next.
👩 MOM IS WATCHING!
Keep using bad form and your mom walks in with a comment — a different funny line for every exercise.
