Right now I'm moving parts of the core engine to the new framework and so far everything looks good.
It is not a secret, that it will be a big task to move everything and I might have to recode or change some of the things from the old version. The UI will be different and better looking. The player movement will also change to have more natural feeling to it.
So the big question is, when will you be able to play it? Honestly I can't say right now, as game development is only my part time job. But I pour all the hours into it that I can spare, so progress is made almost everyday.
