Props on making everything yourself. I personally struggle with making 2D assets.
As far as critiques go, the controls are pretty unforgiving. There's a bug where you essentially stick to the walls if you're midair and open against is. It's a significant enough issue that I really couldn't play past the first few rooms. Only other critique is that the visuals and goals aren't intuitive. It's functional when you explain in text when you're over a shovel, but it's not desirable.
