Quite technically impressive knowing that you built your own engine. And the atmosphere is probably one of the best I've seen so far. Didn't manage to get to the end just yet because the game feels quite brutal, with a lot of trial'n'error on where the limits of the map are so you don't die to obstacles and enemies, but I'd like to finish it.
The most obvious bug I had is that some states and variables don't reset when you die. So I couldn't get the starting quests after restarting. I had to exit and enter the entire application for those things to reset.
This engine is going in the right direction, definitely!
