Fun - There is a good bit of challenge with the game when it comes to tower placement. The inability to replay from within the game definitely takes me out of the flow zone!
Controls - Controls were self-explanatory. It felt a little weird not knowing how to collect things and only realizing it with the tiny blips shooting towards the player. It felt a little unfair without knowing how large the aggro radius was for the aliens and then also being immediately jumped without much of an ability to respond.
Graphics - The opening cutscene was a very nice touch, as well as the death cutscene/ship explosion.
Audio - The audio is good and not too overpowering during normal play. Once you get to a certain point, however, and towers keep blowing up the audio cuts and loops quite a bit.
Accessibility - It's easy to see what the controls are, but it would be helpful to know at the start how to fill the ship. I ran to it at one point to see what was north of it and stumbled into the ship, only realizing I was giving it something with the sound effects.
Originality - Fairly original take on the theme! I enjoyed the tower defense parts aside from dying without knowing how close the aggro range was.
Overall, good job! Game was pretty fun and the cut scenes were a nice little bonus!
