This game is incredible, hands down. The pixel art is great, I loved throwing stuff across the room, I liked how more mechanics were introduced over the course of the story, and the story itself was fantastic. I love how it's sort of implied you were working for the evil empire, or at least that it could be interpreted that way.
Honestly, all the credit should just go to that final level. It was amazing. Everything in the game built up to that point and it was really well executed. I actually had to go back and double check if it was possible to actually beat it, but I don't think it was.
This game deserves to have a full expanded version in the future.
