Thank you so much for trying to play my game and giving your opinion! I understood the issues you had, especially with the lack of a specific goal, aside from buying planets. Making this game alone was already slightly a challenge, especially with a time limit. I did aim for something big, but I didn't really hit the mark in the limited time. After the jam, I will start improving the game slowly. Thanks for the feedback and for the fact you tried playing this mess!
As for the confusion with the cursor and its controls, what would you suggest doing? Because you seem like an experienced person in game development. In the game, there is a "How To Play" menu, which explains the controls, which is what I usually do.
Still, thanks again for playing my game and writing a review, it motivates me! :D
