Also got soft locked at Koltek and in the Knights room (2 Knights, only option is to go to the room on the right which you can't get through because there is some kind of gate thing you cannot roll through.
Some of the boss fights are really difficult., unless I just couldn't understand the strategy.
Having unopened chests marked on the map if you had visited the room would have been nice. The only upgrades I found were a health powerup and a sword one.

The concept with the marked chests is very good, but as for the soft lock with the knights, I can't really get it to happen. After defeating the boss, the main exit is on the left. If you came from the right, the gate should be open. And if you came from below, that means you must have roll, and in that case, there shouldn't be a problem. Either something is actually buggy, or I don't understand the problem. Tomorrow I will try to fix the Kółek.
