Very cool concept, the bosses are very interesting. I hardly know how to play minesweeper though, so I really struggled to get far. Beat 2 bosses, the popup one and the tile shuffling one. Lost to like 3 others before I stopped (That number randomization boss is hell for someone who doesn't know the strategy)
Though, it honestly doesn't feel worth it to do combats from a meta standpoint, I would always just go the path with the most ? tiles. The events don't really seem to have any risk aside from losing money, which is very much in abundance.
Is it even possible for that doll that gives you money when you get hurt to pay itself off? You only have 5 lives and it costs 50, so you'd need at least 2 extra lives for it to profit.
