Thanks for playing, and appreciate your feedback. The tutorial texts are a bit bugged out, the dash gives you a few invincibility frames. So you can get away unharmed when you spawn surrounded by skeletons for example. I wanted to give the player something they could do in combat, since - by design - there is no attack mechanic. Also it's just always fun to be able to dash around a map when you explore.
The ending is behind the last door, you just need to find out how to get there ;)
