I just replayed the game with the fixed tutorial and it's much better now! I think the only recommendation I'd give now is to make the slime and the spider boss have actual audio cues (Especially the slime, since it's very easy for one to sneak up to you).
Glad you like it (: We're totally aware of the lack of sfx in some areas, and it's definetly something we will adress in the future. Thank you for your feedback!
