thank you for the feedback!
thats very kind.
yeah, a menu with pause and restarting current level and choose one of the levels its a nice idea (and easy to implement, i think). you're right and i'm doing it now.
in the last planet, 6, the platforms really disappear, and fast. thats the catch. i think maybe need to add some effects, or add some time. but i wanted the last level to be a little hard, so i really don't know.
yeah, i already made more monster, with effects on the player, but thinked in focus in the ghanges of physics laws, and tryied to make more clean.
thats really the big question to me, if the puzzle elements are enough, too much or repetitive.
thank you again, that's a amazing feedback
