>What was the most frustrating moment or aspect?
When I reached 1500 points, I encountered an enemy(s?) that I couldn't seem to nail down no matter how hard I tried.
>What was your favorite moment or aspect?
There's alot of interruptions in the tutorial, but it's still quite effective in setting a baseline. It gave me more than enough confidence to feel like I understood what was happening until I hit 1500 points.
>Was there anything you wanted to do, but couldn't?
I constantly found myself wanting to be able to visualize the size of the arena, but I never got a handle on when I was at the borders.
>If you could change, add, or remove any 1 thing, what would it be?
A sound for when the player is at the left or right limit.
