I've been stalking this thread and watching the progress for quite a while and I must say it's quite alluring in what you've made so far. I hope you continue to progress with your project and that the Staff can give a thumbs-up to this. However, I can't say I'll end up playing much of this myself (if released) as I do prefer the way FH currently is, and by the looks of it - with all of the shadows and alterations made - there will probably be quite a bit of lag, and those who already experience the lagspikes in the current FeralHeart game will probably experience much more of it in this version.
Kind of reminds me of FH+ though, would love to see if a download for this game, when complete, is put up on the Downloads page.
A good suggestion could be to fiddle with the default animations, maybe come up with something as, a lot of people use downloaded animations due to a disliking to the premade ones. Would be nice to see a change. :>
