I believe that one possibility is to only show the buttons when there is action for them, instead of disabling them.
I agree, but testing is needed here. While the option fell on shutdown. The game turned out to be not easy to understand (because there is no normal training), so hiding / showing the controls would confuse the player even more.
Maybe you are right.
Same is a great game, good luck with it :)
Thank you very much for your wishes! In any case, I added your proposal to my notes and I will check it. Thanks for that =)
