Really impressive, love the different marbles such clever design, the camera felt natural to me, and playing on a controller was surprising fun (I was expecting to be an entry that I had to come back to when I'd dug out a mouse), I would have loved a map or even just a compass in the corner to keep orientated though as was easy to feel a little disorientated (especailly to someone with as little spacial awareness as me)
Played the web version and all ran pretty seamlessly for me I wouldn't have known if I hadn't read your page that any of the rendering was "nerfed". The marble mechanics (which I think are new for this jam) are really clever and I had a (very) brief, look at the slime games and it feels distinct enough to be a game in it's own right, I was a bit worried when I read your game page it was going to just be a cut down demo of existing work. but clearly a lot of love went into taking that core and making something unique for this Jam.
Great Entry.
