How to film it: pick a matchup on the right → press FIGHT → the battle runs about 30 seconds. Today's data loads by itself when the page opens — there is nothing to type in. The circles stay perfect circles at all times and move with real physics — they bounce off the walls, wind back, then dash and slam into each other with recoil and a brief hit-stop, so every collision has speed behind it. On a hit only a small damage pill floats up from the circle — the round's statistics stay in the A / INDICATOR / B bar below the arena and never cover the fight. On some charges a side fires its own skill — Fighter A's rising ▲ CHARGE effect or Fighter B's falling ▼ TRAP effect (LONG: BULL CHARGE, SHORT: BEAR TRAP by default) — a light-and-sound effect only that never changes HP, score or the winner; the data alone decides every round → press Record WebM during a run (or use screen recording) → upload to Shorts. Sound is synthesized live — whoosh on the dash, a deep thud on impact, ticks as the numbers pop, a winner chime — and with SOUND: ON the WebM recording captures it too. Switch SOUND OFF for a silent file. Replays are unlimited — come back tomorrow for fresh numbers.
