- How does the pacing of the game feel, is it too fast or too slow?
The game felt too fast. I could only get to about the 3rd or 4th level before I ran out of time, and I was making a beeline to the modules. - In what ways might we be able to improve the challenge and the 'hectic-ness' of the game beyond the difficulty of the modules and timing?
I agree that adding time when you repair a module would be great, so you're not locked in to a specific time frame for everything.
The room could be more maze-like so you have to plan your route a bit more carefully. Along with that, you could have certain obstacles that would slow Ernie down, like wet flooring or maybe you get an electric shock. - Would you like to see Ernie have abilities/upgrades and if so what would you like to see?
It would be nice to have some sort of time-slowing ability or difficulty adjustment as the game gets more fast-paced - Not exactly game breaking, but I kept colliding with things that didn't seem like they would be obstacles (like little dots on the ground, but I could walk through walls
