I'll make sure to put together a proper devlog as I get V2 ready, but several of those things are certainly on the radar to implement. It has seemed the biggest thing was level design, which I've been focusing on.
Alternate routes is one thing I had been thinking of, for sure. As well as potentially interesting ways to get to the different routes. My ultimate path for release, I think, is going to be mobile devices, so I'll be a bit limited in what I can do for controls, but hopefully will have ironed a few things out to make that more enjoyable.
I really like the idea of shape evolution and hadn't really thought of that. I really appreciate you taking the time!
