New in this version:
Fixes to critical issues that happened under rare circumstances
Added ability to move already-placed enemies/entities (right click + drag in entity placement mode in the editor)
Added horizontally moving platforms (and built a whole level around them that's 253 tiles long!!)
Improved smoothness of scrolling by reducing the range of tiles to render off-screen
Warning: the included level is challenging

Feel free to make your own levels and post them for people to try!
