There are additions to the camera in the arena. The camera gets stuck if the character is outside the arena walls when they appear. This shouldn't happen, but it does. Monsters frolic in the open arena, the walls stand and shock, the character is on the left, outside the walls of the arena, the camera dangles next to the walls. :)
And another bug is related to the NPC merchant. Sometimes dialogue selection lines do not appear, and as a result it is impossible to exit the dialogue and you have to restart the level. What’s interesting is that this happens in certain arenas, no matter how many times you restart the level, but at this level the merchant will always be bugged and dialogue with him will spoil the passage of the level. For me it was Jungle, levels 2 and 3.
PS All monsters in battle are easily passable, except for bees! Bees are an eternal problem! They are 2-3 difficulty levels higher than ordinary monsters because of their shots, which constantly knock you out! Perhaps it is still worth slowing down their projectiles or limiting their flight radius? :)
