A solid 5 for gameplay for you. It wasn't perfect, I think the character could use being a little bit faster, and the controls could use a little more polish. Also, the game is also unplayable with a controller (for some reason, it doesn't go up to top speed on the controller, making some jumps impossible right on the first level). I think the real stars here are the level design and the gravity field ability interacting with everything. The exploratory nature of the levels and open endedness made for a great game in my opinion. Graphics, sound and story were great at building that atmosphere as well. In all honesty, the best game I've played so far. My game was also an exploration based platformer. Controls could use a little bit more polish too, but I think you would like it if you were to check it out (and I definetely could use your feedback!). Great job!

Sorry to hear about your problems with the controller. At the start of Level 1 Lumi is still too weak to reach the first light orb, but gains jump height and movement at a later point and can come back to it . I wonder if that is what you experienced. This was an intentional design decision, but I can see how it might be confusing.
No, I found all the light balls but couldn't make the jump to one of them, the one on the upper floor with some enemies. I just couldn't make the jump, then I switched to keyboard and immediately made it. With some testing, I realized Lumi moved faster with the keyboard than with the controller. So I just finished the game with the keyboard.
