Oh that's quite exciting!
Grove is one of my favorite games and one of the first NSFW ones I've played, so it's always a joy to see its possible future.
The sprite update is something quite nice, sometimes I'd pretty much forget that the armor had broken, so being able to guess that visually (and the possibility for some sprite animations in traps) make for a pretty nice visual update, as I see.
Hope the change in engine goes well!
