Thank you for playing and for the feedback! It's true that if the areas are blatantly marked out then it would remove the exploration aspect, so having a time limit like you mentioned is one good approach. The idea I currently have is an item or an ability which gives hints in general location and then there could be some sort of incentive to only use it if you're really stuck, such as a stat for getting through the level without relying on it. I'm glad you found it fun! :)
