I really like the presentation. The art is well done and I liked certain details like how many things have bear ears on them. I also liked the creative designs for the different planets like how one is a disco ball and one is a flask. The UI is polished. The chill music added to the atmosphere of the game. The controls for the player character are unique and easy to get a handle of.
If you decide to expand on this idea, I think the game could use more to make it more challenging. Maybe hazards to avoid or maybe require the player to obtain specific types of materials so they can’t just grab whatever happens to be closest to the home planet. I also didn’t feel the need to upgrade things other than the speed and carrying limit, so maybe balance it in a way to make the other upgrades more important to require more strategy out of the player.
Overall, nice job! I enjoyed this. It's a cute, chill game.
