Thank you so much for playing it and on top of that; enjoying it! :)
Great suggestions there. I take not of it and if I will do a post-jam update I'll consider them.
The initial plan was to have 10 hand-crafted locations (the final one at the brink of the galaxy) which was the main storyline. Each location more difficult than the previous, and you would need to grind and upgrade to be able to take on next story location. Unfortunately that was cut early because I saw how much time that would take.
