This is freaking awesome. I have started this game at least 8 separate times. I have tried numerous combinations, and every time I was trying to figure out a way to get a Pikeman into my core team (since I am a Warhammer fan and the State Troop Halberdiers were always my favorite). Anyway, your image showed me a Spear I had missed on all 8 of my runs. Now knowing there is a spear there, the Pikeman now makes sense! Going to go play right now.

@mariusz.sabadasz There's no way at the beginning of the game. This door does not open. Access to the upper part of the lighthouse will be by mission, which can be taken very not very soon (there are very strong enemies there)

how to open jammed doors in first dungeon ?

This should take a lot of time and effort, im sure every player with curiosity or doubts about something will appreciate your work on this, I know I do.
