I escaped with the treasure!
So first I would like to mention the strange grid at times. You would have 'doors' that are not centered and sometimes walls that feel way to close when you are next to them. This felt a little disorienting until I got used to it. All those objects were noninteractable after all. But it would look much better if they all would be grid-centered.
My third room was one with treasure, so I found it quite fast (key took a while), but it was insane. There were a lot of hooligans that were trying to smack me. Thankfully I found corner where only two was hitting me at the same time and survived. Rest of the game I was healing up the damage (I nearly died!). I found machete (sword?) and they all started to smack me with sword sounds :) that gonna be a bug ;). I never-ever (especially after having that brutal encounter at start) would wear a berserker mask. Almost whole game I was healing up the damage and getting just 5 more attack for taking so much more damage per hit sounded insane (it was from 17 armor to go -11 or so so 28 more damage per hit, if I understood mechanic correct).
Also you marked pick up wrong! you did (what you picking up) ---> (what you have) it supposed to be other way around or arrow need to be switched. Confused me at the start. Colour coding was nice there though!
But entry was solid. Nice map, really intuitive with all those doors and colour coding in there. Simple, yet effective battle. Had fun :)
