New Mylo Skin

Do you still remember the classic Mylo from the 1991? He's back in his "zombie" colors! During the festive October event, you can play as 'Zombie Mylo'. You can toggle the skin with festive setting but we are also adding a skin selection setting to the game soon so you can toggle between skins without changing the festive setting.

New Level Editor Toys and Tiles

New Objects

  • Shootable Switch Can be triggered only by hitting it with your rockets - hope your aim is good!

  • Reverse invisible blocks Blocks that can be revealed only from the reverse gravity form.

New Tiles

  • New "Pumpkin themed" Terrain tileset

  • Over 15 tiles

New Weather Types

  • Ash

  • Space Debris

  • Rain (Blue/Green/Red)

User Level Browser

  • New category - Oldest Don't bother scrolling to the bottom anymore, jump straight to the oldest maps!

  • Completed levels will now show the "Treasure Chest" icon so you can easily see which ones you've cleared.

  • We cleared a few bugs in the browser, which made the overall navigation more efficient and faster - no more endless "Loading maps" statuses.

  • If the map is downloaded but you're not subscribed to it, you won't have to press the "play" button twice anymore.

Fixes

  • Snowing even when the festive setting is OFF

  • Birds' "egg" drops won't disappear when the player is in the air

Security Update

A security vulnerability has been identified that affects games and applications built using Unity. While there is currently no evidence of impact on users, we’re taking all relevant steps to ensure you’re on the latest and safest version of the game. To keep you safe, we’ve released a new patch immediately after the news that addresses this issue. You can read more about this in Unity's official statement: https://unity.com/security/sept-2025-01 ------------------------------------------------- Maybe this will give you an excuse to enter the Crystal Caves mines again for a session or two. Or maybe, you can go ahead and create a level of your own - we are already waiting to play it! Thank you for keeping Mylo alive by playing Crystal Caves! We're not done yet ːcc_myloː
