Some of the enemies couldn't be damaged, even when they should be damage-able.
When I died, the ship sprite went invisible and I couldn't use skills anymore. I also couldn't figure out how to heal.
As soon as I moved past the barrier of green portals/glowing spots, the sprite rendered for a bit and then I immediately got a game over.
Enemies also didn't get health bars until a later map, where they suddenly had health bars. This was shortly before I died.
I loaded a save I made when the space section started, and eventually I died again and the same thing happened.
In addition, there were a small handful of grammar/editing errors.
The concept is interesting, but there are a handful of bugs that need some ironing out.
