Thanks for checking it out and the feedback!
I think all I'm going to do with this is work on the FTUE, add a bit more clarification about what's going on during the game, probably do another art pass, and mess with the random motion to give the player more agency.
I've had a few funny ideas of where this concept could go. I think the most logical idea is to make a level-based puzzle game and gradually introduce other quantum mechanical effects (e.g. double split experiment and quantum teleportation) to achieve [some goal].
A more ridiculous idea is to take this form of movement and turn it into a cart-like racing game. Perhaps the player has much more control, but the other particles in the race just have to rely on randomness for every turn. I really love the idea of the particle in first place feeling like they're winning easily before a different particle out of nowhere tunnels through a wall to get in front of them, haha. Or like, imagine someone sending a red shell at you and you just turn into a wave to avoid it.
