My absolute fave of the jam so far, I think. Short, sweet, with well-implemented scaling mechanics and an effective story. Enjoyed the music and the controls a great deal.
An extremely minor thing that bothered me a little was when the lizard reaches the top of a ledge I kept falling off if I wasn't trying to move 'towards' the ledge and was just climbing up (if that makes sense). Maybe you already tried it, but it may have felt a little more smooth to control the character if they were given a little nudge to climb over the lip of a ledge.
Anyway, as I said: extremely minor - the rest is so, so good: an amazing achievement in 96 hours, great stuff.
