I'm glad you liked some of our ideas! We tried to leave the game a little bit vague since it was a puzzle game, but perhaps we overdid it. The character always runs to the left when he is out of the light, and that is mostly a leftover from some of our initial ideas, where we wanted him to run to the start of the level if the light left him, but we ended up changing this a bit. We also do have a mechaninc where some things dissapear when there is no light, but just a couple walls do, not everything. It just felt like we could design the stages a bit better that way, but I guess it ended up being a bit confusing, so thats our bad. And yes, I totally agree the cursor should be bound to the light, it is just way more convenient. I friend of mine brought that to my attention when I showed it to him and I was like "Yeah, why didn't we do that?" Either way, thanks for the feedback!
