Helix Discovery: Nuclear Power is now truly nuclear - the blast wave hits every bubble, boss and mine with double your damage and can crit, and it burns away enemy fire - drone lasers, golden coins and spine mines no longer sail through a detonation
Helix Discovery: the mushroom cloud got a visual pplishment
Helix Discovery: your main weapon now stands out from your extra guns - it draws bigger and its aim line is thicker, so you always know which one you are aiming
Project Poltergeist: Neutrinos now shimmer with a rainbow body
Bubbly Arcade: the cabinet shows a game strip under the screen - one lit channel per game with its year, sorted newest discovery first, so you can see every game at a glance
Bubbly Arcade: the deck got proper labels - exit and start under the buttons, and the joystick controls printed beside the stick
Bubbly Arcade: "Your Best" on each leaderboard now takes that game's colors, and your record gets the rainbow or fire treatment when you are in the top 3 or INF
Bubbly Arcade: flicking the joystick slightly off-axis no longer triggers the wrong action - changing game can no longer accidentally flip the leaderboard page
Helix Discovery: the DNA strand between fused weapons now fits and connects cleanly into the weapon slots instead of floating between them
