- Character abilities and weapon slots are now displayed on the boss intro screen, even online.
- You can now right-click an enemy's color icon to go back to the previous color.
- Added Bass to the profile icons selection.
- Two new example levels: Automata Fortress by Nickelasse and Escape from the Space Station Puzzle by Meka, both winners from the level contest.
- Spines are weak to more weapons, all of which were effective against Spine-like enemies in the original games.
- Pressing the Map and UI switches in the editor has been made more lenient.
- Weapon blocks and barriers now default to having no weapon, allowing you to place reflecting blocks with a full weapon set.
- By default, the editor now starts about a quarter into the level horizontally. This allows you to easily expand your level to the left.
- Restarting from the last checkpoint when you haven't touched a checkpoint now acts as restarting the stage, which means ammo gets refilled and tanks respawn. Also applies to quick restarting.
- Charge Man's second background now moves at 60 fps, making it much smoother.
- Enemies, most notably Fan Fiends, sometimes face the wrong way when playing a level online.
- Loading a level from the menu without playing a level first can result in all empty weapon slots getting filled with Silver Tomahawk.
- Brain Break cannot be killed while Flash Stopper is active.
- There is one pixel horizontally where you can active the Map and UI switches in the editor at the same time.
- Tama, its fleas and its yarn balls cannot be frozen by Ice Slasher.
- Mag Fly can still carry you when climbing a ladder.
- You can start climbing a ladder while sliding under a ceiling, allowing you to clip.
- Moving an Oil Slider blob by a jumpthrough moving platform can cause the game to crash under certain circumstances.
- On large resolutions, a bit of Mega Man's blue palette may be visible when using a different palette.
- Elec Beams, Fire Beams and Flame Pillars are affected by Gravity Hold.
- Key Doors can be despawned with pixel-perfect movement.
- Search Snake can clip on certain terrain layouts.
- If you're standing on a solid that's two blocks into the screen below, then move to an empty space, you can transition into the solid and get stuck.
- Magnet Man, Hard Man and Wood Man can't destroy weapon blocks or barriers.
- When standing directly against a wall, Magnet Man can't hurt you with his Magnet Missiles.
- Sometimes you can't enter or change your level name.
- You can clip into magnets sometimes.
- Bosses drop an item when crushed by a moving platform.
- If you slide onto Oil Slider, you can still move below one block tall ceilings for a short while.
- When shooting Gemini Laser directly against a wall, parts of it can go through the wall.
- The Energy Balancer doesn't reliably fill up the weapon with the least ammo.
- Moving platforms can still move you if you're in a teleporter.
- If you slide into spikes while on a moving platform at a specific height, you can slide through them.
