Thanks for the feedback everyone! Glad that it seems people are enjoying the experience overall, even if it's carried a little by the graphical effects.
Completely agreed about the jump speed, @lakrits @real-flamingicecubegames @tigerfinch . I must have got too used to the physics during development, but playing it back now it's pretty ridiculous. Also a shame it felt too easy, have been burnt by making games too hard before, but clearly tuned it too far the other way this time.
@bootak Glad you enjoyed it! Don't worry, the game is meant to be a "hell loop" of sorts, so there's no exit beyond looping to the start.
