It's true, I forgot about them, they were standing too far out of my sight). Fixed it.
I also fixed the sign at the guards' room entrance. Sometimes it was not translated.
As soon as enough time passes, or a few more bugs are found, I'll post a new version here. I don't want to litter here with my flaws too often
Thank you so much for finding the bug!
Can I assume that you are trying to run the game on android?
P.S. As I was writing this post, an idea occurred to me. Can you use this version of the game if you are actually trying to run it with joyplay? If it doesn't break in the same place, please let me know. Looks like I found a solution to the problem of running Koda&Bo games on joyplay (same problem on tower of trample and others)

Edit: Or if you had problems with joyplay, can you try the new version? I spent over 60 hours to fix the cause of this, but maybe I should have cleaned up the consequences first so I could play
