Sup, finally got around playing your game. Had no idea what it was about, and that cover image intrigued me for a long time. (windows partition took forever to update)
I loved the scenes, the colors were great, music and sound effects too matched quite good. Concept is also great, sort of like a hide-and-seek escape, trying to sneak out alive..
Now, for the "negative" side, it wasn't very clear where you could burrow yourself, the tutorial seemed to only show that you do it by holding the mouse left button. So I thought I could do it anywhere, anytime. And when I couldn't do it, I thought it was bugged, or that the controls were unresponsive.
Was able to figure it out eventually, so my experience improved drastically from there.
And lastly, this one is not so important, and probably "rare" case.. which is the mouse sensitivity issue, at first I thought the game was setup that way, but then I remembered my experience with other 3D games in this jam, where I had the same issue, and couldn't be adjusted in game. I think, it may have been my own mouse settings, mine is setup quite high so that I can move my cursor around quickly, specially if I happen to be with a dual-screen setup.. But then again, this is just nitpicking at this point, and obviously out of scope for a jam, but thought I'd share it as well.
