>What was the most frustrating moment or aspect?
The choice of the E key is clunky when the movement keys are so close to it. Another key would definitely be preferred, maybe space.
>What was your favorite moment or aspect?
Manically running around and trying to collect things was engaging.
>Was there anything you wanted to do, but couldn't?
I wanted to be building towards something, which I assume will be added later.
>If you could change, add, or remove any 1 thing, what would it be?
Assuming there are plans to expand the game already, I'd replace the E key with something further away or allow key rebinding.
