This was a fun game. It was definitely strange. I managed to beat the last level after a number of tries and some thinking about strategy.
The background music is from Crusader Kings, so choosing more original music from an open source would be better. I think with some tweaks to the camera angle, or a better skybox, the visuals could be better. I found it hard in the last level to see what was going on at the far end. I liked the concept of the power ups but they didn't seem to come into play much during the game. The text scrolled a little too slowly for me as well, but you could skip the scrolling and display it all so that was ok.
Otherwise it was a fun and engaging game and I liked playing it though. The ending cutscene and plot was an unexpected surprise. Well done!
