That was certainly something, there was no mention of a double jump so a couple of my attemps, some jumped seem impossible that whenever i jumped it would even go into another rock. Even after learning the double jump, there were still issues where jumping once wasn't enough, jumping twice would lead to taking damage or falling into a bottomless pit. 

Oh and next time don't forget to remove the string, cause taking damage shows the, what im assuming is hp, going down. 

Fun little platformer and like the double jump. Not sure if the dev log on the left was meant to be kept in or not.

Jump/Double Jump control feels good, Great feedback, Debug mode text was on in my build?

the rocks killing the slime was a bit confusing to me and some visual feedback of damage would have been nice, Great effort!
