I was just about to take a screenshot of the two characters next to each other and then... that happened. :D It's a shame it takes quite a while to get to the ending because a lot of people will miss it and I thought it was cool.
Most of the map felt barren, but you yourself mentioned the reason(s) for that. A few easy tweaks I would suggest, if you're interested - 1) make the collision shape of the player only around its feet for more realism, 2) allow the usage of the arrow keys or a key other than Q (because Q and WASD are right next to each other so using them simultaneously is uncomfortable), 3) make the lights easier to light up, and 4) make the map smaller and focus more on implementing story elements. Even if you don't want to touch this game anymore (which is basically me after every game jam), I hope it helps for next projects.
