Might as well post here now, as I probably should have posted here while I was developing it: I finished Box Isles, my GBJam 5 entry. Maybe "finished" is not the best word, but it's fully playable if short. It's a simple grid-based box puzzle game. Here's the link.

This is my first pixel-based game that I made in Unity. It's also the first Game Jam game I ever completed. I posted some dev logs here. I developed it to prove to myself I could.
