>What was the most frustrating moment or aspect?
When I realized the slimes don't seem to do any damage to you.
>What was your favorite moment or aspect?
Countering the whole shmup boss at the end.
>Was there anything you wanted to do, but couldn't?
There were moments initially where I thought I had to balance killing slimes and defending from air attacks. Finding out the slimes don't really damage you ruined the compelling nature of finding that balance. I wanted that aspect in the game as soon as I realized it wasn't actually there.
