It seems to be impossible to escape the well. I can't fit through this gap with the morph ability. In general I think shrinking the morph's collision certainly wouldn't hurt as it's inconsistent already for going through flat horizontal gaps. I'd love to play more when this gets fixed!

I tried with keyboard, d-pad, and analog stick. Always the same result. Whether I hold down-left and press the morph button or if I hold morph for a little bit then try to move, whether I'm pressed against the corner to start or if I jump and try to line up diagonally with the gap, the sprite just jiggles a lot and nothing happens. I tried for about 10 minutes and I couldn't get it to work.
