MineDay Season 2

Welcome to MineDay Season 2!
This was a project I made in 2020 intended to be a sequel to MineDay, but with the Minesweeper engine programmed from scratch.
However, I never did much with it, so there are only three weeks here. I just never got the motivation.
That also explains why this website looks significantly worse than the original.
Anyway, here are the weeks:

Week 0: Warmup
Week 1: Double Inverse Mines
Week 2: Odd Numbers
