Pretty fun! I found out you can double jump sometimes, not sure if intended. The Light variable was basically essential otherwise I found I kept falling off the world in some spots.
Many thanks for playing the game and for the feedback :) Yes double jump (but no more than 2 before touching back down again) was intended. I agree for the light variable - wanted to include one variable that the player would really need to get to give them to motivation to try others :)
