Thank you so much for the detailed feedback! I'm really glad you liked the atmosphere and the tension in Day 4.
I see what you mean about it feeling like a final level. A Day 6 with both mechanics would have been an interesting idea, for sure!
And yeah, the choice of E was a design decision, but I totally get that spacebar or mouse could feel more natural. Definitely something to consider for a future update or another game with customizable inputs!
Also, no problem at all, I really enjoyed checking out your game too! It was a great experience!
