Good:
The character was cute, and the reactor looked cool.
The idea was good.
The atmosphere was cool.
The graphics looked good for being low light, which is hard to do well.
Could be improved:
It's nice that there's a tutorial, but it didn't explain the controls
The tasks were confusing and the text prompt was too close in color to the background so hard to read.
The character never rotates, would be nice if it faced the direction of travel.
The theme was not very clear.
The tasks would do well to have some sort of visual feedback for what you're doing.
