Atmosphir Windows, Mac game

Atmosphir is a free 3D adventure hybrid game and design tool for Mac and PC. Originally created in 2009 by Minor Studios and shut down in 2012, it has been unofficially revived by its community at OneMoreBlock through an open source project called Troposphir. Now with a new custom server for sharing levels and in-game multiplayer, users can continue to solve puzzles, jump through obstacles, fight enemies, and collect secret treasures in thousands of unique user-created levels, whether solo or with a friend. Since we've gotten all the major functionality back, we're in search of more creative individuals to participate in our friendly community and design some more amazing levels on top of a great catalog of pre-existing ones. Here are some key elements of the game:

Simple, Intuitive, and Fast Design Tools.
Making levels is as easy as clicking on a block (a platform, enemy, locked door, etc.) and snapping it onto a grid. Atmosphir's design mode requires no prior programming or design knowledge - if you've played with building blocks before, you can make compelling games.

A Deep Toolbox of Blocks.
Add floating skulls, tree branches, extra lives, keys, flying powerups, Aztec heads and plenty of other platforms, props, and collectible items. Blocks are organized into themes and categories, so finding specific pieces is quick and painless.

Thousands of Challenges to Play.
Atmosphir's database is filled with thousands of diverse, exciting levels created by designers all over the world.

Pick-Up-And-Play Controls.
Playing couldn't be easier: use the arrow keys to move, spacebar to jump, and shift to use items. Yeah, that's it. Experienced users can switch to a WASD + mouse setup, or customize their controls however they want.

Games for All Ages and Skill Levels.
Whether you're a seasoned pro or a first-time gamer, Atmosphir has something for everyone to enjoy. Plenty of beginner and tutorial levels help introduce you to the world and controls without worrying about time or lives, while expert levels will push the limits of 3D platforming difficulty.

Share Your Creations and Get Feedback.
When you've finished your masterpiece, upload it with a screenshot and description. Then share it with your friends and family online! Players can rate and comment on your level, helping it move up the ranks and get the attention it deserves.

Play With Your Friends.
Easily join up with your friends or other community members in competitive-style battles across your own designed levels, or cooperatively play together in specifically designed levels that test your teamwork skills.

Expansive Character Customization.
Customize your character using dozens of different shirts, hats, weapons, faces, hairstyles, and more. Earn atmos to buy new costumes for an even greater selection!

A Great Community.
Atmosphir is not a virtual world or glorified 3D chat room - it's a game first and foremost, with a small but passionate and dedicated following. The game wouldn't still be around without its fans, and while development is minimal/limited, we'll always be working to improve the game and experience.

Community Design Challenges.
Are you one of the best Atmosphir level designers? Occasional design challenges put your skills on display for the rest of the community to judge, and the winners are displayed on our forums. We've previously asked designers to make mountains, boss battles, treehouses, racetracks and more, resulting in some of the best levels Atmosphir has ever seen.

If any of this interests you, please come visit us and download the game at Onemoreblock.com. Our forum and Discord chat channel are great places to meet the community, learn more about the game, and share your creations and passions with us. We look forward to meeting you soon!
