were you playing in browser? if you used ctrl+w it closes the current tab/window :P I did sadly the same... retried with using the z/x buttons. To @Jagdoggo - this key binding combination could be disabled in web build and also not mention in the instructions screen, it is very... unfortunate :P The game was pretty hard to play in browser like that but I gave it 10 minutes and had some fun :) Don't know if it's a bug on my end or it's desired mechanic, but do I understand correctly that you only deal damage ramming into guards once you get some damage points from the chests in the castle? It made it really hard to beat them, yet still entertaining :) Didn't fully finish the first castle, but probably would if the key bindings were a little easier to play in browser. Nice game overall, just this unlucky key binding.
