Bring back my buggy cursor update!

What's Changed

This is a little maintenance release. More important changes are coming soon 👀.

• Fixed a bug where the player is not affected by gravity when loading or creating a survival world.
• Fix the block marker.
• The Upsilon version can now be built on MacOS.

The Upsilon version should be playable but there is no official release for now.

Full Changelog: v0.1.6...v0.1.7

Old worlds should be compatible.
