Thanks so much! Clarity with the mechanics is definitely something that can be improved. Also, totally understand your confusion on the exit. That portal is actually for enemies. In order to leave, you have to exit out of the bottom of the map (where you start). I wanted to get some UI element in there to guide the player towards it, but I didn't end up having time for it. Those two pieces of feedback are super valuable though, and I definitely need to prioritize playtesting at every stage.
