Hopefully. BUT, it will be released as a beta. Meaning, you'll be able to build and test, but if you publish it will simply play without the graphics (I think, or it may end the universe as we know it).
This stuff with the platformer is really tricky to do and may cause weird things to happen. My main concern is weird things happening to old games so I'll encourage everyone to test out their old games (but not save them in the new creator)
