Wow, thank you for the detailed feedback!
I'm glad you've liked the contract section, this was literally the first thing I clearly envisioned and implemented in the game.
Also glad you liked the part with the skeletons! This was harder to come up with and took quite a lot of work but was worth it in the end.
As for the language select screen, I have decided from now on to make it a constant feature in my games. It's crucial that Ukrainian and Russian speakers are able to play this game too since it directly concerns them.
