The version I played was 1.7.
I only had a rough idea of how the chess pieces move, but it was very fun because I could learn the rules while playing the game!
Some wands were still hard to understand even after using them many times, but it felt fresh. It felt like I had really become a roguelike character who cannot properly use magical items because of low wisdom or intelligence.
The feeling of despair when enemies surrounded me was very strong.
Later in the game, I realized that when an enemy appeared, if I turned back immediately and defeated them one by one, it was much easier and I almost never got surrounded.
I also thought it could be interesting if opening a door suddenly made the whole room bright, or if there were glowing enemies that could wake up nearby enemies, meow! (=ↀωↀ=)
