Even if unfinished, the concept is fun and it's clear how the mechanics could have progressed. I liked trying to figure out what each pick-up would unlock for the cell and amassing as many as possible.
Attaching the main camera node to the player or at least putting in temporary colliders on the edges of the map would have been a helpful quick fix though to avoid the problem of the player getting lost off the map though.
But otherwise, it's still a cool take on the theme.
