Yeah, I actually drastically changed the gameplay with a few days left on the jam, so it could stand to be more polished for sure! I didn't implement any pathfinding because I didn't have time, but it's something I'd definitely do if I were to do further development on the game.
I would need quite a bit of time in Unity before I felt comfortable trying to make this in it - I'm pretty much a complete novice with it. That said, it would be easier to make the game 3D if I wanted to, as well as implement pathfinding. I'll consider it! Thanks for playing!
