- The online menu has been revamped. It now has a more intuitive interface, along with some new features.
- The level cap has been increased to 20, meaning you can upload twice as many levels as before!
- From now on, the changelog can be displayed in-game whenever a new version is available.
- Added a shortcut for restarting from the last checkpoint. You can do this with Ctrl + R or Weapon Switch left + Weapon Switch Right + Jump + Pause (L + R + A + Start).
- Improved the minimap; it is no longer transparent for better visibility, its color changes depending on the UI scheme and sections with a boss, party ball or energy element are marked with a different color.
- My levels in the online menu has been replaced with My profile, taking you to your new user card. You can still find your uploaded levels here as well.
- Quick Man's tileset more accurately resembles the original.
- Hyper Bomb now explodes after being in the air for a while (e.g. when bouncing on springs).
- Changed the abbreviated names of some weapons.
- Pressing the section toggle icon now produces a sound effect.
- Moving platforms should be more stable now.
- If you pause the game while health is refilling, the sound keeps playing, even if you restart the level.
- If you destroy a Pierobot gear while the clown is falling, the clown will bounce on nothing.
- If you Charge Kick through a boss door with a boss on the other screen, and this boss door is entirely on the previous screen, you can float in the air.
- Teleporting across multiple screens, then touching an element right as you leave the teleporter, crashes the game.
- Switching weapons while only having the Nothing weapon can freeze the game.
- The UI's hand sprite changes when it's grayed out.
- Peterchy's object description has a typo (occassionally instead of occasionally).
- If you Top Spin on a Mechakkero over spikes while it's low to the ground, you die instead of bouncing off.
- Blockies can clip through walls when pushed by a conveyor belt with a specific setup.
- In the UI, the minimap can overlap the scheme change menu, causing weird effects when clicking on both at once.
- The number of shots Crazy Cannon fires doesn't get reset when they respawn.
- If you place a Pierobot directly against a wall, facing that wall, it can clip upwards.
