Thank you for your honest words, and it's great that you liked it! Yea, content is always a big problem in a game jam, especially if you take into account that most people don't play very long, but I agree that in the long term, the game gets repetitive. I would've loved to introduce more enemy types, bosses and levels (after 3 stages, the map changes its color, for example). There could be new structures, etc., then, but yeah, 10 day limit haha
